TODO:
	Blood Crawler?
	Tweak Vicious Goldfish heavily
	Face Monster
	Crimera
	Herpling
	Crimslime
	Blood Jelly
	Blood Feeder
	Blood Mummy
	Deathweed
	Some drops
		Loot items could be implemented as useless powders.
	Crimsandstone
	Fishing loot fish (as Fish copies)
Not doing:
	Mob spawning
	Game-like world generation
	Crafting stations
	Hardmode-exclusive behavior (WoF would be a nightmare to add)
	Biome keys
Might not be possible:
	Thorny bushes (their breaking behavior would require a way for a pixel to detect when another pixel tryMove'd into its position)
	Powders and clentamination (those would require a means of moving through pixels without falsely occupied pixels or other glitches)
	Blood crawlers crawling on background walls
	Brain of Cthulhu (without the rest of the progression)
		*(would be pretty pointless)
		Crimson Hearts are probably possible but would be useless without this
	Actually usable weapons
	Game-like fishing system
	Crates breaking into multiple items
	Tree shaking behavior
	Deadland Comes Alive painting
	Floaty Gross, Crimson Axe, Crimson Pigron (same issue as powders)
Probably possible but far beyond my skill level:
	Enemy pathfinding
	Music boxes
	Crimera variants
	Multi-pixel enemies other than Face Monsters (which would copy human code)
