Pretty cool idea! There were definitely some times that I was like "okay I'm getting combo-ed and I'm totally screwed." The game did eventually get kind of boring / frustrating, as it was a constant loop of trying to get back to the satellite while constantly trying to refuel and getting hit by asteroids and enemies. I hardly got to actually catch asteroids before getting demolished by an asteroid going mach 5. I think it would help to have some way to tell when something is going to come. I did realize way too late I could use the asteroid to block and fly backwards, but then it is hard to shoot, and I was constantly on the brink of empty fuel. It's really cool how the design works so well with these basic components.
