Normal Minecraft, but every 5-30 seconds you get a red light that lasts 3 seconds, and if you don't stop moving within 1 second of the red light you die. You can only start moving again once you get a green light.
What counts as moving?:
Only actual input from your controller, keyboard/mouse, or touch screen are registered, so things like:
- Being hit
- Falling
- Riding something
Do not kill you. You just cannot look around, move around, break blocks, or place blocks during a red light (you can still craft and use your inventory).
Multiplayer:
The addon works fine in multiplayer, and each player has a different random length between red lights.
