You didn't realize it was a co-op game? Wow, dude
I had a couple of guys playing here and I guess it's probably even harder if you have to time the jumps and stuff with a buddy - but it's also definitely more fun!
Yeah, one could just set up different control schemes in the end. Your suggestion sounds good, really, especially since most controllers feature dual analog sticks now - and left and right shoulder buttons.
David just told me that he fixed the Xbox360 Controller bug, so I'll hopefully be able to upload a fixed version later on!
