OK, so as someone who finished the game back when it was released (like few months ago), i will just say this: This game isn't worth it. It has some good art, but the gameplay is crap, there is zero corruption, zero choice to make in the story (aside from 2 minor instances) and all the H scenes are oneshot/non-repeatable which makes this a hard pass.
There is a nice feature where you can just straight up lose to any boss, get boned and the story events will still conclude themselves in an alternate manner (this is good because you will want to skip the horrible, yawn inducing "gameplay"). This can and will fuck you over however once you get to the last boss where things don't work that way, but the ending isn't really worth it anyway.
All in all the game is crap tier and is just a waste of good art...
