omg the zombies destroyed my power plant and i'm out of power! not to worry, i'll just build a new one. oh wait yes to worry, every single method of generating power requires power to build.
this is a great game. the only thing i could think of to improve it would be a "worker satisfaction" rating, and by extension being able to give them breaks and such.
great game, although when i got the autocaster upgrade i saw that it doesnt work while offline. what is the point of having spells cast themselves if it doesnt happen while your offline?
