Pretty simple, but with executed pretty well.
I'm not great at bullet hells, but I'm always up for upgrading the weapons of a space ship. Got 22950 points on a run where I mostly upgraded the main weapon. That feels like the obvious best thing to do, with the two other options firing randomly. But maybe the spiral thing was getting okayish as the density got higher?
I appreciated the forgiving hitboxes while dodging bullets, but maybe the enemies themselves should have larger ones?
I think 3 lives feels pretty intense when there's not so much of a pattern to learn and there are a ton of enemies just filling the screen with bullets in random directions. Take my feedback with a grain of salt because this isn't my genre.
