Very impressive amount of polish and feel for this one! I was surprised at the number of weapons and abilities that you packed in. The visuals are fantastic - simple, but eyecatching and stylish. Excellent boss design, too - each has unique attacks that get tougher each phase, and I never felt like any combinations of attack were unfair or unavoidable.
I feel like I could cheese the bosses a bit with the fire and the spin attacks. The fire charges very quickly, and it massively increases stagger, so I knocked out the last boss pretty quick with it - didn't really use the ice missiles. I could also chain normal attacks with the spin attack to coverup the cooldown for both types of attacks. But that's not really even a criticism - it took some practice to figure those tricks out, and it look and felt awesome.
