Art style and music are really great. The interpretation of bullet hell and projectile use was really creative! I really like the concept and wish it was a little easier to start playing. I think this is a gem of an idea especially for an arcade style game.
Difficulty level felt pretty high because of counterintuitive controls (ex right keys turn you left and having five directional points to keep track of) which made it pretty hard to ease into. It felt like the meteor waves came a bit quickly to start off and the tutorial was a bit of an info dump (ex a lot of text all at once to remember all the buttons). It's a bit hard to reach for left ctrl as well.
Bugs:
Frame rate slows to almost nothing when using spacebar at the same time as a side thruster.
Sometimes the game freezes and can't move forward when changing game modes (ex restart or start).
Tutorial text sometimes comes outside the screen.
