KarBOOM 0.1.2 lets up to four players play with gamepads -- up from two in the previous version. Previous versions used built-in engine functions to handle gamepad control, but in order to support more than two (and in future, as many as you can fit in your PC) I had to use WINAPI functions.
Since I only own two gamepads, I haven't actually been able to test that three or four gamepads work, so this is a cry-out to anyone with three or more gamepads: Does it work!?
As this game continues to develop, I'd really appreciate the input of all its players as I add more mutators, more players, more levels, online play, and more everything in the next few weeks.
