The sprites are beautiful, everything from the character design to UI is gorgeous. I like how the dodge is timed to the attack sound effect. It took a little while to get but once it clicked I had a lot of fun. I think the attack meter might move a little too quickly though. Maybe it can slow down slightly once it enters the attack range. I got an error below when I tried to battle the crab once.

I wasn't able to replicate this encountering other crabs and enemies though. Great work! I can't wait to see more.
