Music - A looping soundtrack plays through the title screen, menus and fishing
Volume controls - Separate sliders for sound effects, ambience and music, alongside master volume. Music defaults to 70%; saved choices are remembered
Bath ambience - A new room recording, with the ambience turned up
Footsteps - A new recording with louder steps
Casting and reeling - A recorded splash when the float hits water, and a looping reel sound while retrieving
Screamfish - A new scream recording; quiet mode still removes the scare
Catch chances - Fish are chosen by percentage chances after a successful landing. The bath and tackle shape the stack challenge independently, so its difficulty cannot reveal the prize
Reel cards - The passing cards use the same catch chances as the prize, without forced rare neighbours
Reel alignment - The fish beneath the centre marker is always the fish awarded, including when the reveal is hurried
