Okay I changed some stuff including the controls, but they're not customizable SORRY. I did what I could before GDC madness.
Updates:

stunned text when players are stunned
smoother end transition back to title
modified hud to hide extra info
modified ending stats screen
dead fish now attract to a near by player
fish now trickle in at the start instead of being dumped in all at once
