I decided in the end that because there were meenlocks all around that would try to pick you off one-by-one, that it would be easier on us all to run it all at once. To add to the already a little confusing scenario these six-second rounds are probably not actually taking place all at once (Crock Jon is earliest, etc) though probably within a minute or two of each other. I just wanted to run it at once, rather than one-by-one.
In case anyone is wondering, I rolled a stealth check for the meenlock that cut the rope. It got a 25, which blows away anyone's passive perception, so I figured no one noticed when it happened. They're sneaky buggers. Besides, I thought it was funny.
