Kill Bricks, Lava & Damage Parts

--[[
	Kill Bricks, Lava & Damage Parts  ·  by Cube Burst Studios  ·  CC0
	One script for every hazard in your game, using tags instead of a script inside each part.

	SETUP
	1. Put this Script in ServerScriptService.
	2. Tag parts (Properties > Tags):
	   "KillBrick"   -> instant death (lava, void, spikes)
	   "DamageBrick" -> hurts while touching. Set a number attribute "Damage" (default 10) and optional
	                   "Cooldown" in seconds (default 0.5).
	3. That's it: parts added later (new maps, clones) work automatically.
