No, it looks like (from the TIGsource thread) that it's dependent on the hardware you're running.
I really like this! I beat the whole game and was surprised that I didn't have more trouble with it, since it seemed like it was going to be really difficult. The only room that gave me trouble was the spike room, but it sounded like everyone had trouble with it. My favorite part were the occasional puzzles that were more about thinking a certain way rather than having pixel-perfect jumping or timing. Like the one area where the solution is to fall instead of jump.
