Nice Graphics, and I like the asteroid the player is walking on.
I first played i full-screen on a 21:9 Monitor but with this setup I couldn't see the tool tip: "press [i] for info" only when I exited the Full screen I could start playing the game because i had no idea how to play before. You might want to fix this, there probably wont be so many players on a 21:9 display ^^
