I'm gonna be that guy and actually post something serious about this game since i watched a playthrough of it to see what all the fuss was about
It just seems like a pretty basic Game Maker game (in terms of it's gameplay and use of stock/standard sound effects, which, this game is almost devoid of even) where it can be difficult to outrun certain enemies, get yourself immediately "transfurred" by interacting with a lot of things, and the boss fights don't really tell you what you're supposed to do (that i know of)
And to get the true ending, you have to make sure to talk to and thank Puro (the talking, black furred, white mask wearing latex creature) every chance you get, then accept the doctor's (whom you've been trying to escape from) treatment before you and Puro leave to the outside world
It just seems like it'd be more of a chore to play than to just watch someone's playthrough of it, and the game isn't originally English, it was translated using Google Translate, so even reading the dialogue can be confusing and painful at times, making the overall experience worse
And the hitboxes are way smaller than most of the sprites, leaving a lot of scenarios that leave you unsure of whether or not you can squeeze past something or if you're accidentally gonna bump into something
Oh, and one of the game over/transfur scenes involving the other black furred, white mask wearing latex creatures is straight up doggystyle butt love, minus any naughty bits
But you'd have to go out of your way for that one, unlike something like Huniepop's suggestive gameplay and even lewder post-gameplay images, so i'm not entirely sure if this game can be reported and taken down for that alone
