I also got the bug where, when you buy a triple hook, it sets your inventory back. The second time I did it, I did it with 0 hooks in my inventory, and when I went back to the fishing hole, pressing space didn't let me fish.
It's a good concept, I LOVE your fish designs, especially the lolligo frixum and great crawler. The game loop is good and I like all the extras. The main character has a cool design and I like how he walks n_n
