This game is top tier! I love the gameplay loop and how varied it is. Fishing minigames can often be boring but you made it into an action segment really revitalized it. The scaling sections were also deceptively challenging! My favourite part was unlocking new upgrades and getting to explore the ocean more and scale the fish a lot more easily. The aesthetics were also delightful - I loved the little characters, and the big fish were really impressive spritework!
My only minor critique is that the fishing hook has a really wide turning radius, which can make it hard to catch the fish, especially early on when you have very little time in the water. Maybe elt you turn faster or lock on to the fish?
Either way, great work! This game was really addictive.
