I loved the game, very original and fun. I found it a bit hard to control, but it seemed like that was what you were going for. Stuff breaking all the time reminds me of my home when I have to fix stuff (like broken door hinges etc. :D)
I would only add a small hop when the spaceman is on their spaceship. It felt weird to me that I could use jetpack in zero-G but not jump.
Great work overall!
