Decent bullet hell game
While the actual gameplay isn't bad, the rest could use a bit of work.
For one, the spheres that fly towards your plane when you kill an enemy are pretty generic. Using an image that's a bit more detailed, or iconic could add a bit of polish. It would also be good to add an image of them to the start screen with an explanation, as I thought they were some kind of flak/bomb at first and tried dodging them.
The sound design could use work as well. Some decent action background music would make playing a lot more enjoyable, and there's tons of music in the audio portal to choose from. Also, the sound made when your plane is hit has a really loud popping glitch noise at the end that's pretty jarring and loud.
A bit of improvement and 1.3 should be pretty dope.
