This was impressive! A lot of things I really wasn't expecting that you could do in an RPG Maker game. Unfortunately I think the was a lot of enemy spam for those normal enemies, which didn't really make me change tactics so much as take longer. Also I couldn't figure out how you were supposed to beat the boss at all - I thought you'd have to keep moving so it couldn't target you but that didn't really work consistently. In the end the only way I beat it was by just spamming projectiles into it and tanking as much damage as possible, which did manage to work at least.
