The animations are really nice and the art is very clean. I couldn't really get a feel for how to eat the bait without getting hooked. Maybe there could be a sprite change for the progress bar to indicate whenever it's possible to eat the bait. Also noticed that you can just ascend into the sky... there's nothing preventing this fish from flying, I guess. Or swimming off screen in general. I think it also might be possible to get locked into place if fish hooks keep spawning in the same location you're in. But it's not too much of an issue unless the player has extremely bad luck.
