Like others echoed here - the gameplay is horrid.
The art and themes are great, even the stuff that I'm not into I applaud if only for how niche and strange it is.
But if there's one thing that is consistent in all of the king's games is that they a lot of unnecessarily convoluted and ultimately pointless mechanics.
There's absolutely no point to the 900000 combat mechanics in this game when you can skip everything with autoattacks.
- That is not to say that combat should be harder; to the contrary. Nobody gives a shit about combat in this kind of game. You have really only two choices - you make combat 'strategic', in the sense that you have extremely limited resources and choices to make as to when to use those resources. Not an RPG, but more in the style of 'you have a bomb, you can use the bomb to get yourself out of a tough spot or you can take 1 point of damage. You have 3 HP max', that kind of thing. Or you can do it more like the better paced Hell After School - again, ignore all the PRG BS and go for something more straightforward.
Grinding to raise 'affection' is still grinding, and this is not the kind of grinding I'm looking for in an H game.
Personally, having 40 different party members seems dumb to me. It increase development time exponentially and I don't really care about their paper thin personality - I'd rather have one or just a handful of characters and more mutations, or a better paper doll system.
