MEGA ENEMIES ARE HERE

Starting with the Mega Slime, these boss-like enemies are now spawnable in levels. 

Changelog:

Mega Slime:

• Has a mana ring which spins around it, which damages the player if it touches it
• Can take 2 hits before dying, dropping any item available in the game
• Hitting the slime itself will cause one damage, and no damage to the player
• If you're within range of the slime, it will spawn mana bombs that will chase after you and drain you of 20 mana if they hit you, every 4 seconds

Minor Changes:

• Added brick particles when you destroy a block beneath you
• Changed particle collisions so they don't collide with the player/enemies
• Increased the max money increase from 25 → 50

Bug Fixes:

• Fixed enemy generation so that all enemy spawn points have a chance to spawn an enemy, instead of only in rooms on the intended route
