I got the cap file from Thomas so I'm gonna look into the crash etc.
The low fps is caused by the 360 controller plugin. I dont know why, but I'm looking into it.
That sound is gonna haunt me forever
I think once it stops crashing, and the lag thing is fixed (probably my fault) and a few more levels get added, this'll make a nice little game
However, I think the controls should be changes so the left stick controls one character and the right stick controls the other. Same with the keyboard...make AWSD control one and IJKL control the other...that way it can be played as a one player game.
