Cool job getting this much complexity into the game within the timeframe. Particularly liked the incorporation of collectivity, different fish, as well as types of environments to fish in that changes the dynamic of fishing and keeps the player motivated to want to fish more. Definitely some cool aspects that could make its way into Worlds.
It was certainly interesting mechanics adding the element of a rhythm input to catch the fish, however, my perspective is that it's perhaps a bit too far from the way in which players in Worlds expect to control their character and the type of skillset required of them to succeed with a game loop.
Really liked the proximity logic built into the interaction between fishes and hook! And giving players a choice of how they fish, and what fish they're going for. Potential for more exploration here that fits nicely with the exploration and open-choice direction of Worlds.
Overall, very cool ideas and great job at getting so much of it in.
