Thanks so much for the feedback! It's really helpful to see what people are looking for.
We set the Kraken as kind of the endpoint for the game jam, not expecting people to play much beyond that. That’s why there are random customers after the Kraken, just to let you get the upgrades and all the fish. But yeah, it would be way better to have hunger keep increasing.
It's great to see that people wanted to keep going, and we're definitely going to take that advice for the next version!
