Nice game, love the animation, good puzzles too. Only thing I can say is for the survive level, if we're supposed to jump and not have to hang, make the platforms closer together, and if we're supposed to hang, make them a bit farther apart. Most of the time on that stage I just wait for the jump animation to stop so I can start hanging.
Also not sure if intentional, but you can hang from mirrors as well.
Besides those things, I think this is a great game!
