Pretty cool, got max upgrades and caught 30 extra to see if there was something secret but didn't find anything XD
It's pretty hard to get going, the jaw speed and extra fish upgrades are way way important at the start since there's barely any fish and it's really hard to catch them.
The aesthetic is pretty rusty and creepy which I enjoyed and also was disgusted by, audio is nice and gives good feedback for stuff done. If I had any complaints it took me a moment to figure out how exactly to upgrade before going back out of the menu and seeing to press the button.
