The issue pertaining to some multiplayer runs is that players are seen moving before the timer starts, therefore making most times faster. Time should start on first movement of any player rather than starting when the recording player begins movement.

unless you are going to run more of this game then i dont see a problem here

But time starts upon getting teleported

what if players leave in start? it counting to players who survived%/death%??

if they helped on the start they will be added on full game run
