Very cool music, and the simple art style fit perfectly. A lot of potential to expand upon.

I really enjoyed this one.  It was a little hard to get to grips with what was going on originally, but once I realized how to manage the ship's heat, speed, and firepower I had a great time.  The visuals, music, and sound effects are wonderfully 8-bit.  I think one of the biggest points of confusion for me is that these is no visual on the ship for when the shield is activated or not, which makes it harder to realize when the ship actually susceptible to damage.  I wish the turret was a little more predictable as well; it would often shoot an asteroid careening by instead of the one about to smash into the ship.  I would to see this idea expanded more because there area  lot of neat ideas and interactions here.

Wow, very cool style of music, the idea is interesting, but not enough explanations

I liked the overall style and the music, but I didn't figure out how to play exactly. I tried twice, before going back for instructions, but even after checking them, I couldn't survive more than 20s :/
