Make the Murder mode! Like in GMod, but on Graal! To whoever who doesn't know the rules, here it is :
There's 1 murderer, 1 sheriff and all other players are bystanders. Bystanders needs to find who's the murderer. The sheriff, with bystanders help, needs to kill the murderer. But the murder isn't so easy to catch: he runs faster, and he can hide his knife. And he needs to kill all other players.

I hope you'll take my idea
