Is there a way to control the rate of alien attacks or are they set to attack at certain intervals as soon as you reach the silver age as long as there's a certain number of them inhabiting the Earth?

I'm going to be bold and start a bug thread here. Please add to it so that the developer can conveniently find a list of known issues all in one place.

Do you have questions about game mechanics, or see something that makes you scratch your head? Post here! This isn't for bugs or for general questions, it's for game mechanics that are baffling or leave you wondering "does it mean this or that?". This is a place for the developer to contemplate design and UI revisions, to see where his players are not understanding the game in the same way he does, since he knows how it works from within his own design....

Just wondering what people are thinking about this title.

Hello, do you have an email address for business enquiries? thanks
