I tried it on Windows. As soon as the prologue ended, I headed to the school and was looking around. Entered the teacher's lounge, tried to speak with her, and it crashed.
I don't know if this happens repeatedly. I simply quit and deleted the file.
On the bright side, for the few minutes that I played, your game was compelling. The characters were likeable. Even the obligatory "best friend" was tolerable here. That's unusual. Most porn games make the MC's besty an annoying moron. It was a refreshing change of pace to have them instantly likeable and actually humorous.
