I really enjoyed this, it's incredibly fun to mess around in the zero-g environment.
Regardless of the result of the game jam, if you're able to continue to flesh out this concept I recommend you do so. I think it has so much potential, I can imagine anything from a longer game with more Zero-G puzzles, to an acrobatic score based game, even an authentic Zero-G fps.
I wish the best of luck with the game jam, and any future projects you work on.
