this is really good, nice job!
I like the gameplay, the controls are nice and simple, and the game teaches the mechanics very well, it's a very simple yet fun, fast-paced game!
however, I did encounter a bug, when I leave the cafeteria, for some reason, I can no longer enter the cafeteria and I'm able to check my locker again, but when I do, I have to do the boss fight against the girl again (I don't remember her name, or if she even has one), it's pretty annoying, however, that's the only bug I encountered.
overall, this is a really good P.O.C., I genuinely can't wait to see what more comes of this game!
