Quick bug fix / gameplay update

Accidentally kept the spawns too high last update from debugging, should be better now. Game pacing is much slower now, and scores will be lower as well. I plan on not having any more balance changes after this so let me know how it is :)

Added:

• Peaceful mode: play without sharks but score isn't recorded

Fixed:

• all spawns were too frequent
• cooked fish no longer float in air
• Eel ability belly glitch fixed
• Keyboard Eel ability enabled

Changed:

• Decreased points awarded from ability fish due to their increased spawn
• slowed pacing for all spawns
• reduced grow speed
• Sharks cannot appear while an egg exists

Next up I will add a new ability, Thanks for playing!!
