Cool idea! Reminds me of my game ;) I wanted to do something like this, with a robot that builds itself and then breaks itself down for different situations. I didn't get it all done for the jam though.
The physics of your entry are kind of funky. The robot parts got split up and then stuck in different parts of the world. Sorry to say I gave up after that. The idea is def a good one though.
The hand drawn art is also very nice. Good job!
