I think the premise is really neat and well thought out. I also think there could be a bit more depth to the combat. Perhaps the trident continues moving after hitting a fish, allowing you to spear multiple fish with one shot if you time it right. The combat was difficult enough to keep me engaged for a while, but there'd have to be more to it if you turned this into a full game. The concept is really solid and the art made the experience come together nicely. Good work!
