Got stuck at the top here, no idea what caused it, but I can't move out of that spot:
The bullets I shot also stopped making any sounds after a while (when you get at the four tuber girls I think). I was using the multi-shot.
I assume that the detention part isn't in yet? At least it wasn't clear to me what to do there.
Also, when using ESC to pause, pressing resume doesn't do anything. Pressing ESC again works.
Anyway, I like the concept of the game. Can't go wrong with a big tits shooter.
Edit: On closer inspection, it just freezes your position when starting that part of the mission regardless.
