Game Claus Quest Hacked (Cheats)

Hello!
This is my first attempt at a game, building off of Adv. Micro Platformer by @MBoffin and The Lich King by @dollarone. This game came about as a gift to a friend (Claus, obviously) for his birthday. Consider it a WIP, as bosses are unkillable and there is no way to actually win the game.
I would greatly appreciate any help on these matters:

--Bosses have no hitpoints. Current enemies have one HP. Bosses spawn but can't do damage or die (unless they fall down a pit). Would like to be able to set health for different bosses and maybe even for some of the enemies.

--Knockback when taking damage, both for bosses and the player.

--Token optimization.

--Projectiles. Would love if one or two of the bosses could throw projectiles or fireballs.

Thanks to Dollarone and MBoffin!
Enjoy!
