Make touching a spike hurt on a beat, and leaving and returning cannot dodge it

Standing in a hazard should hurt every so often, not on every frame. But a cooldown that restarts when you step out lets a player hop in and out, and one shared cooldown lets a second hazard hide behind the first. This entry keeps track per source.

Why this works

A danger is something the player can learn: it bites, then needs a moment. Giving each source its own wait that keeps running whether or not you stand in it means no trick of stepping out and in changes the rhythm, and one trap cannot hide another.

When not to use it

Skip it when touching a hazard should simply be deadly, such as a pit or a wall of fire, or when the player already gets a short safe time after any hit. Then one rule on the player is enough and simpler.
