VN - Ren'Py - Completed - Bottle Biosphere [v1.2] [KuMoNoSuGame]

If you're a romance enjoyer like myself, then this game is a must-play. Stop reading the reviews, go back to the post, download the game and have your heart melt.

While the game isn't very long, it does take a long time for the girl to finally start opening up due to her trauma while you have you manage your time working a part-time job, buying food to not collapse from exhaustion and actually getting home in time to spend time with the girl and interact with her.

The thing I liked the most about this game were the major decisions during the turning points of the story. While I won't go into spoilers, when compared to other H co-habitation games this game does set itself apart with some of the things that you do and can be really subversive.

That being said, the game isn't without faults. First of all, the game is kind of janky especially when it comes to events. For example:

- You hit the requirements to trigger an event during Saturday, but the game refers to the day as Sunday or you trigger an event during the morning, but the scene takes place during the night with no actual time passing.

- Very often you can trigger an event after waking up or coming back from town, the event happens and right after it you get the generic "good morning" or "welcome back" scene as if it was all just a dream.

- If an event trigger is an action (for example, showering or going to bed), the action will not count as being triggered leading to things like going to shower > you end up showering in the event > event ends > oh I guess I didn't actually shower so I need to do it again.

There's also a chance-of-injury system, where you might get injured during work and have to skip a day in the hospital and pay 10k Yen meaning you lose progress and the chance to interact with the girl. It's not a very fun mechanic and even though there are *some* rewards being tied to it (with the girl giving you permanent buffs later on), you're still better off savescumming before working just to not lose progress and have the game be artificially longer.

My last gripe would be the progression sometimes being confusing. For instance, there is a laptop you can buy which can give hints on how to unlock the next event/scene, but it sometimes references things that you simply haven't unlocked yet with no way of knowing HOW to unlock them.


Even with these faults in mind, it's definitely one of the best romance games I've seen on this site, would definitely recommend.

The Latest Update is Buggy that even the Demo Version did better.


6/10 CG - The Interactions and Scenes are mid and it lacks dialogue that would make them special except the 1st Sex.

7/10 In Game Mechanics - The designs and the way I can purchase, make money, etc. are beyond satisfactory but it has a lot of bugs in translations or even interacting with objects, plus applying for a different Job method is misleading and confusing "You can use this for something" isn't something helpful.


9/10 Art - It's good but again, there's bugs especially when the Runaway Girl falls asleep in the floor.


Overall, the game has a lot of potential but the CG interaction and mechanics need to improve, the bugs needs to be fixed, the translation could use some work, the game could make it easier to guide players how to apply new jobs using the objects in game.

8/10 the game is good. have a nice art and history, but comparing with 10/10 games it is lacking in text enverironmet, the soundtrack it's not the best in the word but make it's paper. In general is a slow sex game with a cute shine girl, i'ts a good call if u like games like teaching felling or mdrg.

Basically if you like the fantasy of a cohabitation game with a hint of tragedy then this is the game for you. There's really not much I can say about this game because Ive played so many like this with the same premise, gameplay, and H content, and this game is not pulling any punches in being just another generic cohabitation VN. But whatever, here's my own review on the game.

You play as a random guy named Ryosuke, who lives on part time jobs but somehow never seem to have money issues. One day coming back from work you spot a girl slouched on your front door. Yes, this tiresome trope has been played to the death so you dont need me to explain any further.

Gameplay is VN style, choose the right option or lose the game. I will praise the gameplay for at least tying up with the story. You need money to pay rent and eat food, besides also buying stuff for the girl Fuyuka. So the grind at least has relevance in so far as the story is concerned.

H gameplay is a VN spacebar masher. There's little to no interactivity in the sex, just spacebar yourself to submission. No animations, and the pics are barely serviceable. There is VA though.

Art style...well its okay. Its just generic anime fodder, complete with long busy hair that shelters Fuyuka's face like a poodle dog. Basically speaking, if you like anime designs then this will not disappoint though if you want anything more youre not getting it.

If you reached this point of the review youd probably be wondering why Im still giving this a 4 star rating, and that's because the story saves the game, and is presently the only reason why you should even bother playing it. The tragic past trope has yet again shown its face but damn it if it didnt do the job well characterising Fuyuka's story, there's literally no holes I can think of that the story hasnt got it covered. I wont spoil the storyline for you, but if you can suspend your disbelief that Ryosuke did not call social services on meeting the girl then it plays out incredibly well. Even the fucking doesnt start until much, much later, so there's some attention to detail; girls in real life dont fuck you after two days living in the same house, something which is never true in japanese anime.


So...in conclusion. I can only recommend this because of the story. If you like your H with a healthy dose of good storytelling, then this game will reach down to your soul and caress it gently. However, if youre the kind of guy that doesnt need context to get hard then this game is just a middling generic game that may not even work out for you. Its not an A+ in art like 1room, not unique like teaching feeling, but more than capable of standing on its two feet.

I wish there were more wholesome game like this one, not full harem nukige garbage, even if there are some visual bugs with the sprites and the story is not better than teaching feeling the game is completely playable on 1.2.

Loli single heroine for the win!

This game will get a bit of a weird review. The story and art are incredible. It's incredibly wholesome and the voice acting is on point. However, there is a significant controversy surrounding this game, that its code was stolen by a forum member. Speaking of the code, it's not well written. Such games which heavily rely on a UI are better off using unity as an engine. The game has frequent bugs and the translation is a bit iffy. But considering the art and story, it's a 10/10. Fuyuka best girl.

A really likable character stuck in a grindy and bloated management game, with inconsistent design choices, bugs, and hallow mechanics.

The menus lack consistency and seemly have sub menus for no reason, such as the Bathroom > Take a bath > Bath / Invite Fuyuka when there is only one option in the bathroom, there is only two choices in the take a bath menu, and ultimately it doesn't matter if you invite or not it seems.

The issue of menu design wouldn't be as annoying if the game wasn't by design really grindy and repetitive. Later in the game you are just trying to push along to find the next bit of content that the first half of the game so kindly baited you into.

Then there is the issues of the clothing and bugs related to that. First off the clothing you pick for her does not do much, she wears it for that day only then it resets to the default basic shirt or seifuku, and that's when things go well, some items you pick will crash your game out of nowhere due to "missing assets" and if you didn't save in the last hour or more (like me) well, you're SOL pal.

So many of the design choices are different depending on what menu you are on, it seems like the dev decided on one thing then later while working on a different aspect, wanted it different but didn't wanna go back to update his previous choices. Such as the hair salon purchases showing what you unlocked with a confirm dialogue box, and most every other unlock just giving you a quick toast popup.

Ultimately I hope this developer can learn from this experience and take the otherwise nice designs but make a more thought out product.

Broken game, crashes every new day. loads of bugs and the dev is sus. could have been great, but i guess ill never know since it is unplayable.

short reviews have merit and the strict polices here prevent alot of user contributions.

I have no idea why its rated so low, I guess because a lot of people rated the demo. Well, the full game is exactly what you want if youre looking for this genre (saving girls).

You take a runaway girl in and slowly bond with her. Unlike some others in the genre (1room runaway girl and runaway girl and me come to mind) you dont dick her within 5 days of meeting her. The entire story is a bit darker. When you meet her she is pretty far gone. During the first few ingame weeks she barely communicates with you. So if you have a savior complex this is some "I can fix her" gold.

Now, the animation is a bit extreme and doesnt look the greatest, the art is a bit rough around the edges, you dont really have any stats to manage, the english is a bit rough as well (grammar and spelling mistakes), but it doesnt really matter for me. The quality of the story makes it easy to forgive. Its pretty amazing to see her go from an emotionless husk to a peppy girl thats all over you. And the author knows how to pace it, she doesnt bounce back in a day or two, she slowly starts to trust you and requires a lot of encouragement before she dares to trust again.

The game is alright. Great story but i feel like when you have sex outside of the story, its very boring. Like no sound and its just pictures. Not my cup of tea but very good story and money system etc.

This game is an emotional roller coaster at certain points and those emotions shine through even with the slight English issues in the text. I would say the grind is a little much, this coming from someone whose grind tolerance is insanely high to the point where I don't mind most games with some level of it, even blatantly high levels. Fuyuka only gains a slight increase in her affection, romance is the actual stat name, per headpat or other action and this leads to it taking an extremely long time to get her to open up to anything else. However, I do not feel the grind is enough to knock off points.

Takeaways from the above:

1. definitely recommended for players who like story.

2. NOT recommended for players who want a "fuckathon" style game where there is more focus on sex at the cost of quality in other places or where there is zero story. Also not recommended for people with low or no grind tolerance.

3. Be prepared for emotional moments, both tearjerking and anger inducing.

I have waited for this game since the project was started 2 years ago. I'm so disappointed I cannot say by words. Especially cuz this was my first pornish game I played back then and I really enjoyed it, but the final product just a mess and nothing more.

-The first thing: The dialogues for the only 2 characters that this game have is just non existing(Yes, yes both of them uncommunicative but this is no excuse for a game which is trying to tell you a story). You grind for a half hour with pointless clicking, just to get a new scene, but the only thing you get from the girl is "-Ah bro we cool? -Yeah, we cool, now let me pat you". I played 3-almost 4 hours and the only change I got that I can date with her where I can watch a pitcure of her with no dialouge. What's the point of going on a date then?

-Let's say something about working in this game, cuz you gonna do this 99% of the game. Full of crap the whole. You do nothing just watching a picture for like 10 seconds and not even a cool mini game, which would be understandable if you didn't need to work this much or if there was any good interaction with the girl or some sort of story. Ps: The rent is increasing every week just cuz why not. Nothing more but frustrating.

-And after this the game don't really have to much scenes too, and the worst that I didn't even got 1 after playing 3-4 hours (except the rape ending one), and I'm not even talking about sex scenes: No kissing, no starring, no flirting NOTHING. Ps: After you closed the game once, it cannot even remember the name you wanted and the game will not refer you as the deafult name, it refers you as "Player" nice.

As for now I cannot recommend this game to anyone and I don't really think the dev gonna add new scenes or anything to this game, which is breaks my heart. I would rate this game 1* but the art is really good. Nevermind, the game wastes your time so much, I can't give 2* either.(Sorry for my broken english, I hope my points was clear enough tho)

Last update: I'm finally finished. At the end of the last 10 minutes the game just crowd everything, dialogues, and the 3 sex scenes. 1 of them are completly static, 1 is okay I guess but the art is weird there and the last one is animated which is pretty good. But you see this game is way too "long" but it has only half an hour content and the remaning 3-4 hour just a waste of time.

Really huge improvement for this new update it feels lesser the grind especially with the new H scenes its actually is worth it.
Really love this genre of games like helping up or raising someone it feels wholesome.
I hope this game, runaway girl and teaching feelings we'll have more games like this in the future.

Ps. Sorry for my bad engish

really laggy sadly, sometimes when I use the space for reading through the convo, after it it just kicks me out of the game so I am forced to save like every minute or else I risk to have to play it again. And furthermore the skip button does not work even turning it on since I already know the first parts of the game.

tdlr: Sadly unplayable as it is right now, forced to use space while it doesn't work as intended and no skip available....

The game's OK so far, nothing out of the ordinary I'd say. Other than that, graphics are a plus, really like the clean black with green accents for the GUI, but I don't know to say if it's befitting or not, as it makes the game feel a bit more like an inspiration off Persona. Albeit, it may be a nitpick of mine. The gameplay is relatively simple, mostly managing your resources, that being money, food and thirst. Although I feel like this could be improved upon, maybe lowering the rewards for some? (Working, Eating food, maybe diminishing returns kicking in?) Or making time more scarce, making the game a little bit harder, but manageable, but does give off the immersion of "being a poor person yet choosing to help someone". But then again, that's maybe not the design choice the developers are going for. I haven't checked out the sex scenes yet.

I haven't played the versions before v2, so I'm running on what I've seen in this release. The mechanics are solid, and the UI is pretty clean. Story is good so far. It's a classic narrative in these sorts of games and the dev does it well. Loving the art as well. My only complaint is that there are currently a few bugs surrounding time based triggers, but they're pretty easy to navigate around.

All in all as long as the dev gets the bugs in check I think this game is going to turn out great. I already really enjoy it as is tbh so I'd definitely recommend it to anyone who is a fan of this genre.

There is nothing here you haven't seen in screenshots.

Buggy, devoid of content, most options do nothing and you feel it's not a demo but alpha version - barebone UI, one or two sprites and two images + 1 H-scene that makes flash games look like absolute king of the hill.
Demo would be chunk of real game cut out of full version. This is not demo. This is proof of concept.

If you feel like getting baited by pretty image go on, your choice. This game won't get any update in coming years. Probably ever.

i'll give it 2 star for now. so many bugs i counter in single hours. not even reach 10 days. So far this game so good! i have played this game in previous update and it's awesome! i'm recommended you guys to try it, but when the bugs got fixed

It's good for what it is. A demo. I really love the ui, it's the most clean and refined. There is only 1 scene and it's not yet implemented properly into the game. I think this might become one of the better games of this type. Well we will see if it will.
Understand that this is only something like a prologue. Nothing major happens and it doesn't even have proper"simulation" yet. They only thing you will do here is get to know the characters and that one scene/not-scene that you can see in the screenshots.
