Nice job on this one! Really cool animations and art, I especially loved the death animation. It fits very well with a Magical Girl theme. It's quite short, but what you've got is polished. I wish there were more opportunities to mix up the ranged and melee attacks, especially with the boss fight. I found myself mostly swimming to either ends of the stage and using the ranged attack hoping that the boss would run into it. I loved the detail of the mermaid statue being a save point, make sure to keep that in there if you keep developing the game. Nice work!
