I've made a small test setup for a game of murder in MC using some signs and a bit of redstone.
If the project is successful, I'm going to make a full scale build.
The game rules are based on wink murder (http://en.wikipedia.org/wiki/Wink_murder), and are simmilar to those of gmod murder as they have the same origin.
Everyone is free to play at ./warp murderdemo
Warning: I was not able to protect the build because of residence plugin issues.
DO NOT GRIEF OR I WILL REPORT YOU INSTANTLY!
I will be adding pictures and future updates.
