Got a chance to play through it and I'm mixed.
It's obviously high quality but I fucking Hate Donnie. Or at least I hate Donnie having sex scenes and the idea of sharing love interests with that fat fuck. I hope we can break it off with our "fuck buddy" we share with him as MMF's is not what I'm looking for when I go for a harem game.
Other then that, the humor is good, the girls are all varied and interesting but the focus really needs to shift away from Donnie. I know the MC is the main character but you spend ALOT of time on Donnie... which I hate because he's a fat buffoon who's fucked just as many if not more of the females then you... which is not what I look for in a VN.
But yeah, shift away from Donnie, tone down the insinuations that all these people have all fucked each other, and you've got a great little game. If it keeps going as is though... eh.
