Not sure why people are beating on the writing, I actually found it to be quite engaging...
The atmosphere in this game is very well done. And the balance of horror and eroticism was pretty nice, especially in that early scene.
As far as erotic games go, I generally hate being the bad guy, but the main character was written well enough that I could actually identify with him, at least to some degree, most of the time. Was still hard watching him being mean to the girl (and realizing what he apparently might have done to others), and don't get me wrong, I'm not exactly on his side - I mostly stuck around to watch how he gets killed by the creepy girl. But he still felt human and understandable enough to follow as a protagonist, even if I'm rooting for his downfall...
Overall I think this is a very nice first chapter. Might not be for me in terms of kinky stuff (though I might enjoy it when the MC gets his comeuppance, if there will be a horror/erotic scene like that)... But the atmosphere I felt was worth a praise, good use of music, nice tense moments and good general ambiance. Was worth a read.
