It could be so much better. My main concern is that as you continue, your "cube bot" gets smaller to the point where the player can no longer see it. There's no way to get hurt, so you can only continue jumping until you give up. Even after you stop jumping and fall out of view, the game continues. There is no proper way to "die" as the asteroids do not injure you. If they did, some major tweaking would need to happen, as they are too big and move too fast for the player to react until the "cube bot" gets to be pixel-sized. Also, poor presentation made me believe I was going to be playing a platformer, but when I fell through the asteroids I thought it was a dodging game, and when I took no damage, I lost all reason to continue playing. On a lighter note, the music is nice. I would've chosen a different font though. The current one is somewhat hard to decipher.
