Cool little game! I like the art, characters and that you wove the environmental issue into a little story.
The game stopped 3 or 4 levels in, I'm not entirely sure if it was the end or if it was caused by a bug. I think it could have benefited from a little more developed fishing tools on further levels and that the overfishing somehow became visible in the mechanics, but I know time is ofc limited during the game jam.
Great job either way, love the art!
