I got sucked into this one and played a bunch of runs. I still haven't beaten wave 10, but not for lack of trying!
It definitely took me a while to get used to the ship's inertia, as well as the fact that I didn't actually want to be dodging bullets much of the time. I hit a bit of a wall in my first few runs, but once I started using dash as my primary attack, things really opened up. I feel like the timers for spinning and dashing are perfectly calibrated for the waves of enemies, and you can kind of settle into a rhythm with them.
Super-fun, addictive game, and a really cool twist on the standard bullet-hell formula. I had a blast with it. Awesome job!
