This game isn't too bad, but there are some improvements that could be made: add some music, add some indication of when the end of the game will be (like a map or distance from space station, etc.), and increase the difficulty. There were hardly any UFOs and some weren't anywhere near the path you had to take. Also, it was a bit annoying that if you jumped over the screen you automatically died. For a character that jumps so high, that's a bit of a pain.
