nice, i like it! feels like a great foundation of amazingly-smooth flight controls (seriously, just the act of flying around while just vibing feels nice) and surprisingly warm aesthetics (for how minimalist they are) to build more on top of :)
one thing i'd like is to have directional sound for the enemies - the red arrow alone is not always enough to tell where you're being shot at from. also, speaking of sound - i REALLY enjoyed the music. seriously, it adds so much.
