Do not use Max HP and 0 Damage together as this will cause you to take damage extremely rapidly. It will be 0 damage, but unless you want to hear an annoying number of hit sounds a second, don't do it.
0 Damage While Shielded requires you to have shields.
No Jump Limit requires you to have at least 2 jumps. At least 3 jumps recommended.
Force Double Jump allows you to double jump right away. The table defaults to 3 jumps for compatibility with No Jump Limit. (Note, you must jump and land at least once after activating the script to activate it (triggers on landing).
