Green Kills You

Contact with green blocks ends the player's run at once. The death check covers any part of the player's body, so even a slight contact with a green surface is enough to trigger it, and the list of qualifying blocks extends to dyed variants, plants, foliage, moss, emerald storage and oxidized copper. Damage from green contact cannot be avoided by ordinary means, and armor does not stop it, though armor resistance can give a second chance in some cases.
