Tiny Tower keeps building up, up, up! Developer Ian Marsh tweeted last night that the addictive tower management title had reached 10 million iOS downloads. The company previously mentioned it has a million daily active users. It can't hurt that the game doesn't cost anything, but that's still quite a few folks building up tiny office structures!
Tiny Tower, named Apple's 2011 iPhone Game of the Year, recently brought the fight to Zynga for its liberally inspired game Dream Heights. Whatever the legality is of such games, Apple is starting to take notice.
