I'm pretty sure you are already aware of this, but if not, here's a bug. If you keep jumping with the 2 player, you just keep going up. And with that i also found out that the 2nd player doesn't take fall damage.
If you are wondering how to start the 2 player mode, just go to the school dorm. and use the racer game there.
Other than that, niiiice mod, me and my friend have been wanting to play bully together, but never could.
Sorry for my bad english.
