Here's a warning: This is not a normal adventure map, it relies heavily on the story which is from "creepypasta.com" so cold blooded fighters 
may be dissapointed.

*No destroying or building blocks
*Only use items gained from chests

*If you want a challenging quest then play with monsters on and in that case take the swords and armor sets from the chests
*If you would like an experience as close to the story as possible then leave all weapons and armor in the chests and play on peaceful

If you want really good atmosphere then use a mod that lets handheld and/or dropped torches emit light as well. Any texture pack should work
I personally used painterly while building the level.

Have a nice adventure ;)
