I've just reached 90 on my population because they just wouldn't stop mating like rabbits. However, I now need a GC to continue with the other puzzles, but I can't have anymore children as I've reached the maximum population I can have. Is there anyway I can speed up the dying process? Can I kill villagers at all?

If you play at 2X speed, they will age quicker.

How do you get to 2X speed?

You can set your speed in Options.

thanks
