I like the idea and the presentation but it was a bit too difficult for me. The later levels feel like they go too long without a checkpoint for the amount of tricky jumps required to beat them, which leads to frustration as you have to replay the start over and over just to get to the bit that's giving you trouble. The jump also feels a bit unnatural as there doesn't seem to be any conservation of momentum.
I'm glad I got far enough to see the level where you control 2 characters simultaneously, really fun implementation of the limitation!
