What a lovely game. I would love to see it expanded a bit with some more mechanics. Especially the fact that you have a timer where you can dangle would work well with some timing based obstacles such as slinging rocks or goats. I am really inspired now to do some physics based projects! I could also imagine using 4 keyboard buttons to engage/disenage specific hands/feet so you can do some real pro moves, kind of olympic speedclimbing.
