The presentation here is fantastic! I loved all the effects, the pixelated water physics, and the music. I also really liked the twist on fishing using a UFO where you have to help the fish instead of picking them up.
My only issue is it does get fairly repetitive at times - I'd really love more levels like River where the water affects the fish and the garbage - but that's understandable for a jam game.
Overall it's a fantastic game! Definitely deserves to be expanded on.
