Fun game, I don't think I've seen anything else submitted with python, which just makes this more impressive in my opinion, it was fun to mess around with and I think you got the weight and physics just right to make this equally fun and frustrating.
I did run into a problem where clicking and holding down would cause several things to trigger at once, as one thing went another would fill it's place and go too. I suggest moving the activation to a mouse release instead of on press.
Overall fun game!
