Mr Brown (Horror Map)

This is my first ever map and I decided to make it a horror map.
Description:
You are a detective sent to investigate a case on Mr Brown's island. The family had complained that he had not visited them for a long period of time and the forensic team could not identify the source of his death. YOU are the only one who can find out what happened to Mr Brown.
Info:
This map supports two players. (but solo is better)
This is my first ever map
The map is on an island.
RULES:
Difficulty has to be peaceful
Gamemode has to be survival, if your hungry bring some food with you or use a command like /feed
Credits: MasterOfWafers (I made the whole idea of the map, did most of the building and all of the command work), Nymphz (Built the entire fireless mountain and made some of the tunnels and added decorations), MrMagic4628 (tested the map).
PLEASE report any suggestions or bugs in the comments.
