I found a bug, too!
On the 2nd mission, where you have to double jump over the cliff or wall thing, and at the top there is a buzz saw. I jumped over the saw, and accidentally hit it anyways. it sent me flying, and trapped me INSIDE the wall!! Then, it wouldn't let me out... I tried everything I could think of, but I was still trapped! please fix the bug. other than that, everything was awesome, better than the 1st one ;-)
