Ah okay, because it immediately prompted me with "right click", i assumed that it was time already to right click, and then I thought maybe it's about timing it with the fish that I can see in the pool and maybe pulling back at the right time, so I attempted that a few times and in the end i just didn't give it long enough.
I managed to pick up a fish and two cans! Beyond that, I'm not sure there's much else to do in the game.
I really liked the aesthetic and the concept, I think maybe the execution is missing a little magic to keep me hooked. I'mma give you 4/5! Great stuff
