The game has a really strong concept, and I love seeing things from the crab's point of view. The visuals, and the water sound definitely gets me excited for the summer!
Some things to consider:
1. The bars decrease really fast.
2. Screenshot below, most of the time the space to jump was working fine and at a point, it took me really high up in the sky where I was over-watching the entire scene below, as if I was a flying crab.
Good work :)
