THE GOOD (what i liked, and what stood out for me):
I liked the concept, and as far as I am aware, it is very unique! The rag-doll physics are spot on, and the music's pretty groovy. I also liked the inclusion of satellites in the level and precision required in the game, which makes it very rewarding
THE BAD (what i disliked, the bugs, and other problems):
Unfortunately, the game lacked sound effects and was quite clunky. For example when the ship hits an asteroid it just disappears, no particles or animation, just poof. The game, in my opinion, would have been better suited for last year's theme "out of control" with minor tweaking, since moving the ship by the smallest amount can create a vast array of pendulum motion that makes the spaceman pretty much impossible to control after wards, it makes the player want to move very little.
THE HARSH (stuff that would just make the game better, usually just personal opinion, don't take it too heavily :D ):
The spaceman was too small, and the game could do with a few more unique obstacles, and perhaps some parallax background art?
OVERALL: A well made, unique, game. A solid 4,5,3 from me!
