Nice game. I've played it for weeks already.
I think there is a minor bug in the world dominator though.
When I activate the world dominator at rank 0
it reduces one mind by 1 whenever I enslave something for example North America.
After I prestiged the world dominator is always available, but I still need at least 1 one mind to enslave something, but then the game doesn't take the one minds away anymore.
Besides that I'd recommend the factor 10 for bandwidth and No. of ads.
