This was so close to being really good! I *really* did not like that the boss could turn the arena into ice physics. It almost felt like death was inevitable if there was a bunch of bullets everywhere. I also did not like that the charged spin attack took mana. It already takes time to charge the attack AND spin it. Mana didn't feel like it was needed to balance it. I came so close to beating the boss, but unfortunately didn't do it. I still think this was really well done despite my personal gripes.
