Okay so first of all, this game is much better then the score would suggest, theres plenty of much worse games with higher scores.
That being said there's plenty of wrong to, like the entire amelie blackmail thing, I mean I do generally prefer the MC being dominant, but I can still appreciate a good blackmail story, however, a story where the MC basically has to do humongously stupid things in order to be blackmailed is not good and just forced.
I also feel like the MC's personality is all over the map, he enjoys dominating lily but also enjoys getting used by amelie, he's fairly intelligent for most of the game, but a complete idiot when interacting with amelie, and he's respectful almost to the point of bringing down the mood with trianna, but with lily she just needs to move her leg a little and that's all the consent he needs. And yeah lily told him that's what she wanted, but trianna also basically shoved her naked ass against the MC's dick and mounted him a couple of times during the fight, so...
Also, that butterfly was pretty random, lol.
But taken as separate story's, I greatly enjoyed both trianna's route and lillys route even if lily's route felt forced at the start. And again, there's many games out there with higher scores that are much worse then this one.
