Exchanging works for most of myselfs
Hands/arms are controlled with keyboard and mouse

Current features - Instancing array of the player and any objects (with any delay) - Arm controls - Grabbing and throwing
My two main ideas for the actual gameplay are - A imposter hidden among yourselfs trying to murder you (he could make mistakes and only come closer when you don't look.) - Using your other selfs and items they might hold to solve puzzles. Which could also include sacrificing them for instance to channel electricity somewhere or to activate traps.
