Wow, really enjoyed that one ! I really loved the music and the mood of the game even though it has literaly nothing to do with space ? Except maybe you have 3 spaces to drive on ? Meh
Anyway I feel it's a great perfect game ! The only thing I would have to add so the game feels a bit better, without thinking of the theme, would have been to use more the space around the game area. It's a bit empty and the only thing you have are red squares. With a different choice of assets like blinking glowing mines for instance and some particles flying everywhere and changing color with the music or something, we would have a very pleasing looking stage to drive on!
Also on another note, try to make the game more visible if you have the time. I played this because in rated games it is in the bottom and that's how I choose to rate a game. If it had at least just a screen of the game, many more people would have play this entry. It is a shame because it's a good entry
