Nice variety of bosses, both visually and mechanically. The bullet hell on the first boss became a bit intense after I had lived for a while, since the missiles were moving slowly, I had almost no space on screen and just started tanking hits while desperately trying to finish off the boss. It was still a fun fight, though.
The characters look nice, the backgrounds cool, and the color palette was nice. There were SFX for everything I'd expect, which is nice. Finally, the music was quite good.
Cool game.
