I dig the music. The game is like Atari's Enduro, but with a twist. The controls feel good and there's a tension while you see that counter diminishing. I think there should be a number of hits you could take before blowing up so it's not that unforgiving.
I'm always curious about these "Outrun" kind of games - I've never looked at how they're made, but I bet the code is something interesting to look at.
I wasn't able to get too far, but I enjoyed the game overall. Good job!
