Punching the enemies away is fun. For the the shiny pearl was always in the same spot, maybe you could switch that up. What exactly is that claw powerup doing? It felt like it didn't do anything. I like the boss art, the big jelly crying looked cute, reminded me of something but I'm not sure what exactly. I also felt like that I got hit by the big jellys lightning thingies even though I thought I dodged it. The movement during the boss can be a bit awkward, not only is it grid-based but it's also automatic. I feel like it might be a better idea to make the boss similarely based on the grid. Might be worth to try out.
