Stealth Run is a map where you must remain invisible. No question. Becoming visible can be deadly. Different variants of stone do different things, but you will have to discover what they are by yourself. If you die in this map, you entirely restart. I did this because it presents a challenge. Even I find it very difficult, so I made a room in the spawn where you can warp to levels. This map isn't a very long map, but since it quite difficult and you have to restart every time you die, it could take a very long time to beat.
