Advanced version: The game mechanics does sabotages, certain sabotage-fixes gives the crewmates extra points/tasks in task-bar like imposters can turn off lights switch and if crewmates fixed lights, then they gain 3 tasks finished/points as a team. Maybe the imposters can even undo pressing hands in Reactor or undo typing codes of O2 by crewmates by typing themselves correctly. Or classical path, can kill the crewmates on the way,
That's (probably) impossible to do this without modded protocol, yet just shared my thoughts.
