Yep, I'm sorry for this, optimisation & performance was not in my mind during the jam.Thanks for the feedback and glad you played the game!
its no biggy just thought it was funny almost had the pop reg to 3 so they were coming out of the wood work.
There is a limitation to 100 people at the same time, and I've upgrade the code few days ago to upgrade the perf but.. not enough I think!
