Very neat idea, and both the controls and graphics are pretty clear! I enjoyed flying around, although felt at times that the fuel was draining very fast (for example, I would have liked to be able to aim left/right without needing to use fuel, so that I can line up "jumps" to other stars).
My only complaint: whenever I run out of fuel and I want to start again, I'd like to jump right back into it to try again!
