Ohh thank you, I haven't though of that this is actually something that can get you stuck. I'll fix that and see if this can occur at other parts, too!
I don't quite understand your problem with the jump though. I tested a bit and I assume that you maybe mean that the player gets too much speed too quickly even when pressing just for a brief moment? I see why this makes very small jumps difficult. I think I can improve that ^-^
I actually agree on your opinion on the triple jump. However there're quite some areas where you'll need them or where they make your life a lot easier. But a double or even triple jump is much more user friendly in this case and probably also more fun. I'll probably change that soon and try not to break the current level designs while doing that :'D
