5/5 - Amazing
To be honest I don't think most H games or even visual novels for that matter have this much effort that this game does. The game tries to be serious but also light hearted and switches between the two perfectly.
Part 1 - Humor 138/5
The biggest stand out of this game by far is the humor, this game has some subtle and not so subtle humor that is so good. This is the last place I expected to laugh but some of the stuff was so funny, I don't think I've found something so funny in at least a year or two. That's despite me constantly looking for humor, whether it's videos or whatever.
Part 2 - Art 5/5
The art in this game is pretty great although maybe a little generic, at least the style is. However it's definitely top of the line if you're into the style, it keeps the same style throughout and it's always high quality. There is one other aspect to the art I haven't seen people mention and that's the environments and atmospheres. (extremely minor spoiler ahead, so incredibly small that this doesn't even need to be added)
During some sections of the game you are traveling and the places you travel to feel completely unique and different. It's a breath of fresh air but it's not just those places, everywhere you go in this game has a theme that it does very well.
Part 3 - Sound 5/5
This isn't something that I usually care for but this game actually does have some sound whether it's ambience to add to some of the darker settings or sounds with specific intent or even if it's just some music that occasionally plays. It's all done well and it doesn't feel forced or ever get annoying, it adds to the experience without taking away and if you don't like the sounds, renpy has a decent sound system.
Part 4 - Characters 5/5
Each character in the game is unique, they all have different and sometimes relatable personalities. Some characters have struggles or some growth and others are more for the humor (another minor spoiler but it'll mean very little to you unless you've played a bit plus it's pretty obvious right away but it's here)
Such as everyone's favourite character Stabby Mike, the comedy machine himself.
Out of every character the one I feel has the best growth is the main character. Starting off kind of annoying or a cringy after the first big story event he really develops into an actual related, understandable and interesting character. He is by no means ever that bad but he goes from a bit generic to a really solid character.
Part 5 - Story 126/5
Now obviously if you look at any other review, you'll see how much they mention the story and it's very good. It's a little bit of a psychological horror thriller kind of experience with some supernatural aspects which just help the experience a lot. If I had to compare it's concept or idea I'd say it's along the lines of Parasyte The Maxim, a bit of horror, a bit of supernatural but at the end of the day that's not the point, the meaning is more the point.
The concept itself is a bit overdone but it's done in a way here that it doesn't really feel over done, it just feels like you kind of know what to expect at first until you get a tiny bit in. If anything that's my only compliant about the story is that until you're about 45 minutes - 1 hour in, it's not that great but not that bad it's just whatever. Regardless it picks up and keeps the same pace throughout. And although the ending is a bit disappointing, that's more because you wanted more from the characters especially the humorous ones not that it was actually disappointing. The ending does exactly what it should, it ends it and doesn't try to do more or less, it's not offensive and it's what you should have expected. That's for the cannon ending or rather the Harem ending.
Conclusion
It's good, it's funny, it looks nice, it's thrilling, it's surprising, it's fun and it's funny.
