What was my favorite moment(s) in the game?
I really loved the unique (at least to me) movement and mining mechanic. I love physics games and this one hits me just right. The graphics is very good for a game of this scope. It gets idea across easily and does not distract from the experience at all. I liked the shop also since it gave me a reason to keep playing and gathering more minerals. The sound design is really good to, gives a nice feedback to actions.
What would I change about the game?
I personally thought it can become frustrating when there are no more meteors on the screen and I have no where to go to. Since it is random, some runs this is expected, but it was happening more often than I would have liked. Another thing I didn't like was that it was difficult to go to a shop and even when I did manage to get to a shop and buy some stuff, quitting afterwards made me float in space without any way to go to a nearby meteor.
Overall, I think this is a really good new concept and just needs some little balancing changes.
