I had fun with this - good movement and the collisions work really well for something with such an oddly shaped environment put together in a weekend.
I did have similar issues to sub-rosa when it came to running the game, though. The crank being docked/undocked at boot didn't seem to make much difference - the odd thing is that the same did seem to be running, but the display was not getting updated. I say this because if I hit the home key to quit out then the game would suddenly refresh the display (so I could fire an explosion, wait a couple of seconds, hit the Home button, and the player character had moved).
Not sure if that is useful information or not. Honestly not sure what would cause it to randomly get into that state or otherwise just run perfectly normally - I'd go off and play a couple of the other Jam games, come back to it, and suddenly it was behaving itself normally.
