Okay, just played this and I feel like it could be promising... A few thoughts:
I am going to assume that bad shit happened to Sam. The token black best friend killed off before the game even begins, that shit is dark!
Seriously, though. This was really good, very well done.
It seems like Ava and Annie are the only Love Interests in the game, I hope that the player can choose who the MC does or does not fuck or enter into relationships with. At minimum the player should be able to determine who the MC fucks and when. If the player can make decisions that actually impact the storyline and the MC's fate I will be very happy. On that thought I hope that the player can have the MC end up alone but happy, the character shouldn't be required to be in a relationship to be happy.
As to cheating/NTR
I don't believe it is NTR since we have no reason to be jealous, though the MC is obviously jealous. Regardless I don't care if Ava says that she stripped naked because she spilled a drink on herself and just fell asleep next to Bryce. She was down to fuck and ready to cheat. If people can avoid Ava then it will help mitigate a lot of complaints, however if the MC is required to talk with her, build a relationship with her, then I understand why people will be unhappy (and constantly complain). Cheaters can be forgiven but that doesn't mean you would ever get into a new relationship with them.
I played the scene with the bratty kid twice, when I helped the mother she handed the MC a piece of paper but the MC never looked at it or did anything with it. I hope it will come up soon.
The interstitial/title sequence with the MC floating in water should be removed or moved to the beginning of the game. I almost quit the game right there because I didn't expect it to continue.
I'm going to guess that Ava isn't the girl who fucked up the MC's life (since Annie didn't recognize Ava that means she isn't the woman in the picture or known to her), which means that he has two separate and completely different relationships which caused him to be fucked up like he is now. I hope that you contrast the two fucked up relationships with something happy from his past (not only his friendship with Annie).
Anyway, I am very curious to see where this goes next. All of the above is just my shit opinion so take what you will from it. The story interests me and I look forward to the next update. Good luck!
