The more I've thought about this game, the less I've liked it.
The first thing that should be obvious, and isn't really a criticism at all, is that this is simply not a porn game. Not even in the porn-with-plot sense. It's more plot with occasional smut, but even the smut will suffer to help further the plot. It mostly bears mention for being mixed in with so much porn. It's not a bad thing, it's just different. But if you want one and get the other, you probably won't be too happy. Hence, mentioning it first here.
On to the actual criticism.
The biggest problem I have with this VN is that the format (VN) just doesn't work with what the intended goal is. VN's are particularly good at increasing the connection between the player and the MC. It gets very self-inserty very easily. They are also pretty bad at complexity. There's just not enough words to do too much. If you grab a big old novel and just slap it into a VN line by line it would be awful. These are just things you get, and give up, when you use the medium. But in this particular game, these factors combine to more or less rob it of it's point.
The VN is so focused around the MC being emotionally traumatized, even unstable, and the fact he needs immediate and direct support. The problem is that between the high degree of self-insertion and the lack of complexity, it just feels wrong. It's like you're being told you, the player, are actually in the middle of some emotional crisis and are actively falling... except you don't even know why because the VN hasn't even told you yet. Instead of being an emotional experience, it's more of a bewildering emotional blank. The self-insertion ends up fighting against itself and ends up just leaving you confused.
Then the other bits. This contributes a bit to the above, in addition to being kind of it's own issue. Everything happens with maximum drama. It's falling down on the floor crying as another character says they've been through similar things too and it's fine and you'll get through it too and yada yada yada. The people are are all "I'll always be a little broken, but I can be happy now!" and that kind of jazz. And it's pretty constant. This just amplifies the inability to connect with the MC, in addition to being kind of grating even with the other characters. There's just no break from it.
Well, there is. It's the final major criticism I have, actually. The breaks. The VN doesn't go to cuter, lighter moments between the main cast once the maximum drama needs a break. If it's the main characters, it's maximum drama. Instead, the breaks come in the form of some random meaningless side characters that stay around for far too long with a single slapstick routine that just never ends. I don't care about them. They don't matter.
So instead of getting through the over-the-top drama that you can't really connect with because you don't even know why it is that you are currently on the floor apparently a half-step from contemplating suicide again, and then getting rewarded with a nice cute scene of the main characters actually experiencing some of that happiness they keep claiming they've found with each other... you get to go spend nearly equal time with a few random mooks that just repeatedly get beaten up in absurd ways.
I can see what they were going for, and it isn't a bad target but... it just clashes so hard with the medium, tries way too hard, and then doesn't give give you the promised payoff. Just... no.
