Gameplay: Cool physics game. I like the mechanic of using physics to solve puzzles
Graphics: Quite basic, but I imagine for a game like this, the core feature is the gameplay mechanic and not the graphics. I would have something else in place of the green squares (something like a glowing star field etc.)
Audio: Music was ok; could have been more atmospheric. I would have loved to hear more SFX for the rocket, its propulsion and its crash.
Innovation: Very nice!
Theme: You place moons in certain areas.
Overall: Excellent game mechanics!
