I really like the visuals you've created. It reminds me quite a bit of things like Tempest 2000. Like others said, I can't quite figure out how to progress. I can get as far as the level starting to rotate but by that point I'm out of ammo and can't shoot the red obstacle that curves into me. I'm assuming there must be a mechanic or trick I don't quite understand so you might want to start players off with a little more time to get acquainted with the controls. Regardless, this is still really promising and looks great!
