Thank you for the kind words! :)
I actually didn't have time to code in a spawning method for the fish schools, so they are hand-placed. I also didn't have time to check if all of them are accessible... oops :D
They have quite the generous collision shape though, so even if you fish around them, you might hit them.
It was really tough to balance the reeling mechanic. On one hand, doing it with the keyboard is REALLY hard (I got good at it eventually, but it's a quick shortcut to carpal tunnel syndrome). On the other hand, if you do it with a controller, it's too easy - especially if you're using a joystick and not the D-pad. So if you're having trouble, grab a controller for easymode.
I actually wanted to implement an "easy reel" mechanic for people who found it too hard that would just use Up and Down to control the hook, but I couldn't get around to it. That's why the options menu is nonfunctional :D
