Nothing you did was wrong, my team and I unfortunately ran out of time to implement the tutorial so there is no way you would know that you need to left click on the swimming fish in the water to cast your line. Thanks for your feedback and let us know your thoughts if you come back to the game.

thankyouuu!!! on second revisit i noticed I had to double click as well, but after that the game was super relaxing and chill!!! i don't mind the fact that the levels take a bit longer to progress through but if you guys end up making a post jam build with a different way to reel in fish (such as a minigame like in stardew valley) lmk because the atmosphere is unparalleled :)
