Very fun! And very cool interpretation of bullet hell. I liked how moving the player ship feels (the movement felt very ... boat-y). Visuals and audio are simple but effective. I wish the camera would zoom out a little once you get to a new wave with bigger enemies, or that the easy waves in the beginning would be shorter once you have some upgrades so you don't need to wait as long for the difficult enemies to appear. But that's honestly just nitpicky stuff, you did a really great job :)
