Me, designing it a long time ago: Having an optional boss fight as a random chance to trigger when you fish in a certain spot with a certain type of bait is fun! Cool idea!
Me, trying to playtest everything again: oh god just let me see the boss, my bag is so full of fish!
I officially declare today "test play day." I'm going to waste the whole day playing video games, which isn't a shock to anybody, but hopefully today I'll play my own and figure out what still needs fixin's.
added a Panic gauge to battle. it fills up according to your actions. each character has a different passive that activates once the gauge is full. also once full, a countdown starts and after each action taken, the gauges decreases. with each character, the decrease is different.
