This level feels... unfocused. It wants to do many gimmicks, which range from tile 1F0 to dolphins, but I feel neither is really executed well. There doesn't seem to be any interesting sprite setups; I get that the level focuses mainly on Chucks, but I feel their potential isn't really used. Tile 1F0 is really only used in two setups, which consist in jumping around in a sequence of enemies. The introduction isn't bad, but it's overall lacking. There's only one setup which uses the eating block.
I'm not sure if the level is salvageable, to be perfectly honest. It really needs a revamp, especially because right now there's no focus on anything.
