This was really nice! The fish felt fun to control and it was nice zipping around the level, jumping over hills, etc.
I did softlock myself at the very end by jumping over the last hill only to get stuck behind it haha. But that's just on me exploring too much. Overall I think this was really well done for only being made in a week and I think it'd be neat to see this movement with more mechanics like a small collectathon or sonic-like setup.
