"Worse yet, those are the ones I make the girl take all acts to the next level, with another guy!"
Now it's race as you try to take all her firsts she can give them to anyone else!


Overview

• Calendar-based Progression
  • You go through parts of the week, each one serving a different purpose
  • 4 seasons, 10 weeks/season = total 40 weeks from game start to ending
• Weekdays (Club Search)
  • The goal is to find which clubs the FMC will attend for the whole week (Mon-Fri)
  • There is a "puzzle" game where you can guess the order of clubs she'll go to
  • Guessing a correct club to a correct day advances your vanilla intimacy, with romance scenes
  • Guessing wrong advances the bad scenes. See Corruption section.
• Saturday (Story Event)
  • Saturday is for main story events, unavoidable story based on time of the year (holidays, etc)
  • Branches scenario into vanilla or NTR ~~depending on...~~
  • All scenes for the whole year are already laid out and planned.
• Sunday (at home)
  • Sunday, she sits on the couch, this serves as gallery for event replays
  • Can make heroine report any scene from any previous event
  • Can play missed Vanilla or NTR alternative scenes (through imagination or roleplay)

Weekday Puzzle Mechanic

• Heavily inspired by
  You must be registered to see the links
• You must be registered to see the links
• You need to guess a combination of 5 clubs
• If your answer is wrong:
  • It will say the number of clubs you guessed correctly in the correct spot
  • It will say the number of clubs you guessed correctly but in the wrong spot
• You get 10 chances to guess the combination.
  • Any time you guess the correction combination, even before 10th guess, you instantly win
  • If you didn't get the correct combination even after 10 guesses, it still checks correct spots
  • e.g. If you guess 3 clubs on the correct spot, you will advance vanilla on those 3 clubs, advance bad on the 2 wrong clubs on the wrong spot

Erotic Overview

• Whenever you make correct guesses in weekday gameplay, it will advance VANILLA scenes.
• Each club you accompany her on will have its own scene line, and progress independently.
• Scenes get increasingly hot and spicy, wearing revealing club uniforms, and sneaking away.
• She might even service you discreetly on a corner while other members aren't looking.
• The goal is for you to win enough, do things with her, take HER FIRSTS, before anyone else.
• Win more, take her firsts, before bad scenes progress and get ahead of you.
• Yes, bad scenes can get ahead of you if you don't win enough, and others might take her firsts.
• There will be many FIRSTS. There will be a way to track it, and it will be **very detailed**.

Corruption
Owen, the student council president is the villain, who is after your girlfriend, Nana.
Whenever you fail to accompany her during weekdays, he will approach her.
Bad scenes will progress depending on how many times you fail the weekday games.
It will start very tame at first, club members taking candid photos of her, etc.
Eventually, her guard will be lowered, and club activities get increasinly, daring.
Progress far enough, Owen will join the activities, and they will get intimate.

• You will see on social media photos of Nana in increasingly compromising situations
• The posts will have threads with comments from other club members and additional photos
• In later stages where she's engaging in full-on sex with... you will receive video tapes

The Catch?
She's totally aware of it, and even tells you about it after things happen.
She's not actually being corrupted, just getting more daring, pushing your buttons.
She teases you on what the Owen and the others saw and did to/with her.
Yes, she knows you like it because she read your chatbot roleplay conversations.
...and thus I call it Netorase.

Clubs
There are 8 clubs at school, each having a unique line of events (romance and NTR/S).
During these events, she will usually wear outfits related to the club's activities.
When you guess wrong during weekday puzzles, bad scenes will progress.
Each club's scenes will progress independently, increasing in intensity, more daring.

Will you actually date the girls or will you be only friends? because for me it's not really NTR if you are only friends.

 

[melantha]

Will you actually date the girls or will you be only friends? because for me it's not really NTR if you are only friends.

yes, the idea that the mc is also trying to raise his ♥ towards the girls means they are romantic interests. and with enough ♥ and choosing to go home with them, there will be after school (non-ero) date scenes.

however, if you are trying to raise only one fmc's ♥ and accompany her everyday, that girl will surely never get any NTR scene, and is vanilla. BUT the other two will surely be target of "NTR" but in this scenario it will not feel like it because you dont care about them?

this explores the idea that most "routed" VNs are possibly NTR. most games routes will end vanilla, but never told you that in that route, other girls would have found their own love eventually in their life and get it on with other men. what if we move it in time that the unchosen girls are held by others during the time of the game. if this happens in games like yuzusoft or whatever cute VN developer, it will certainly be called NTR, just the fact you showed the imagery of potential love interests in other routes having sex with others. at least to me, this feels like NTR. by technical definition it may be not, but it invokes jealousy to the "player", not the mc. so theoretically, you'll want to get harem route lmao

Here, let me ask the next most important question, the CGs.
The CGs, in my opinion, are the game's strongest point after the gameplay.
So, how are the CGs? Are they drawn? AI? Or a collection of hentai images from the internet?

Anyway, you've got a great concept, and I'm rooting for you.
Bookmarked

hand drawn by me, 2D anime-style.

though I admit I have never drawn erotic stuff before, only clothed. but I'm trying to learn, recently tutorial by mignon on coloring skins. I shall post whenever I can.

likely the initial images will only be sketches, just to give people idea more of the concept rather than art

thank you for support, this is a good feeling to work harder

 

[Creamzo]

Complex system you've got going on here, and an endless NTR game sounds awesome. Is this something you'd intend on continuously updating? I will watch with much interest, Good luck!

 

[cIoseopenbrutal]

Nice concepts! Good luck on the game dev journey.

Adding to the CG questions, can you show us a bit of your art? Just wanna see your art style.

the good thing about the game is that the gameplay loop is extensible.

since there's a day cycle (unlike linear VNs), on further updates we can just add new clubs or events, and they'll just be added to the pool of possible places the fmc can go to everyday.

im not yet thinking about the release vs appends, but my preference is just to add limited clubs at first, probably starting 3 or 4, then just add club/event one by one after.

thank you

thank you

right now I'm starting on the technical side, programming the foundations of the game (im not using a full game engine, only similar to a renderer (HTML5/Phaser) but the systems have to be made custom).

thus in terms of art, it will be some time, but I'll probably have small roughs of the events first, to show how vanilla scenes will be different from NTR scenes, before I can show any proper line art

 

[cIoseopenbrutal]

I see.
What I meant was ,do you have any (character) art drawn that's not related in the game atm? I'm just curious on your general artsyle.

 

[melantha]

perhaps, this very rough draft would suffice for now?
just disclaimer, the real game CGs will have actual line art and coloring

this is concept for the art club, which is especially revealing among the clubs btw.
other clubs wont be this revealing in early club ♥ stages.

the images for ♥20 ♥30 ♥40 will appear on the in-game SNS after school

the idea for NTR surveillance is that it will have the same POV for ♥60 ♥80 ♥100
there is another student taking the pictures / leaving cameras in club rooms.
you will have to buy these photos from a user in a forum after school. (still have to figure out currency)
the characters CGs in the room will be bigger in reality. I just had to fit the 3 scenes in 1 box.




other than this, I might make a big chance to the concept soon.
having 3 heroines with their own CG on each club multiplies the amount of artwork needed.
will have to cut it down to 1 FMC, with a story that in the end, they START the neutral club.
Neutral Club 2 can be the game with 3 FMCs.
I just need to start small and see if the game wont fail, and if I'm meant to make games.

 

[melantha]

Here's a couple more roughs for 1) non-ero (just features the dress of the club), and 2) vanilla scene.

In these events, I'm going for the "unfair" feeling.
The MC's ♥100 club scenes, will not show the fmc's full body / privates, and are non-penetrative, such as handjob, footjob, sumata, etc.
It will also be emphasized on the dialog. e.g. "I could only see her in a tracksuit when I'm there, but she shows her swimsuit to the other swim club members, and even let them touch." (again, this only ever happens if club♥ > mc♥, so chill)

 

[cIoseopenbrutal]

I guess you dont want others to know about your previous artworks ,which is fair.

Nice drafts btw. Not a big fan of gangbang ntr( unless it's the reversed kind) , but I still welcome it.
I wont say much for now as you're still in the early-stages.

Edit : Regarding about gangbang scenes , I do like them when theyre all kids aka shotacons banging the heroine. It just adds this layer of sadism in me where kids can get the goods, while the mc can't.

thank you for understanding. this name is specifically for R-18, and I'm just entering the sapce.

currently there's only 2 clubs with MMF/gangbang, out of 6.
the other clubwill be either another single student, or coach.

I do like the idea of replacing MMF offenders with younger actors, will consider it, thanks!

Well tought concept. If you can do it well it will indeed be a very atractive game. But as other people said before you can´t avoid having good CG so go nice and slow with the drawings. Hand drawings are good, even if they feel a bit amateur (AI still make people feel uncomfortable).
Now if I can give you 1 suggestion i would say that making a whole group (club) the enemy in an NTR is a risky move. Most of the "works" in NTR use a rival concept (i mean there can be a lot of rivals but they don´t work together because each one want the girl for themselves) so doing it with a whole clubs as rivals might limit your reach to the players.... That being said this is your game and if you want to see the girl being seduced by a group go for it!!!!
But still I would suggest having another factor to atract those who look for more common NTR games........ how about this:

If group exceeds 20 corruption points he will speak his troubles to his best friend (normal guy, normal size, decent personality) and say how his crush is being seduced by a bunch of people because he is unable to guess the correct club everyday. As a joke and a way to refresh the mood the friend will suggest his help with his quest since the friend is in the go-home club. The MC considers it but realizes he just has to try harder

If group exceeds 40 corruption points almost the same thing will happen but in this case the MC accepts the suggestion at the end. Then there are two people that can stop the corruption.

Now the friend system would work somehow like this. The MC will say what club the friend will go to, then if either the MC gueses right or both of them miss then the game goes like normal. But if the friend goes to the correct club then the friend stays next to the girl for that period and wins points for himself...... Let´s say +6 each time. Now that´s a lot of points but the trick is that at the beginning of each day the MC will have to chance the ask the friend for the events of the day prior and that will remind him that his actions are for the sake of his friend and that will lower his points -4 at the beginning of the day (If the player doesn´t remember it stays +6). The same as the club and the MC the friend system will have events when reaching 20, 40 or more points and the friend get the girl if he obtains 200 points before the MC

Now the drawbacks of this will be that this is like adding 25% more work in all aspects so yep that would be troublesome to say the least. But i can assure you that something like this will atract more players so it depends on you..... this is just a suggestion. As the creator this depends completely on you and just you have the final word

thank you for this amazing feedback!
it did cross my mind to have a main antagonist, but I didn't bother much to think about.

but reading this, you do have a point that 1v1 NTR has a certain "hit" that immediate mmfs don't, and can attract more players. certainly I will evaluate it and try to weigh in if that extra "hit" feeling is worth adding.

though in this train of though where there's a main antagonist, im thinking more like a male Student Council President (blonde ikemen), as he also has ability to roam freely in school grounds during club activities. He's also aiming for the FMC and % chance he will find the FMC if you don't.

I'd like a blonde ikemen because I want the FMC to fight back and stuggle at early stages, but will, little by little, submit to his charm, looks, and sex skill. this is unlike old ugly antagonists that only win the fmc over by sex. I believe antagonist winning FMC over in more ways will have certain "hits" also.

Doesn´t sound bad at all. I would suggest to do just that. If you go with something you like you will put more entusiasm while creating the game than just following the words of someone from the internet XD

Plot seems interesting. I'm a sucker for the gf finding mc's secret kinks through internet searches or doujin or whatever. Is this still being planned or is it abandoned?

hi, glad you find the story concept interesting.

, and i just added her trying to fulfill those roleplays leading into netorase scenarios.

the thread was posted 2023, but behind the scenes it still went through months of refining the concept, but i just can't find that gameplay device that will make everything work. spreadsheets upon spreadsheets of ideas, but i just mulled over without acting.

eventually moved on to other ideas and even started on those too.

recently, i tried to look at this again and had a newfound interest in continuing it. i've finalized an actual gameplay mechanic concept after so long. and with the power of AI art (which i wasn't aware of its power in 2023), im confident i can now make this work.

so even though the post was 2023, i treat current time as the actual start of the project's development. i look at it like 2023 was fertilizing the egg, and now is the time to hatch it.

i even think that huge gap in the timeline is a blessing. over those 2 years, i have learned alot about AI gen and am excited to bring this game to life with a much better quality than i would have back then, when i planned to hand-draw everything.
