NimbleBit's Ian Marsh revealed that Zynga has developed an iOS title very similar to NimbleBit's popular business sim Tiny Tower, pointing out numerous design similarities in the image above (click for full size).

Marsh notes that Zynga once attempted to acquire NimbleBit, presumably to earn the exclusive rights to publish Tiny Tower and earn revenue from microtransaction sales. Zynga previously purchased App Store developers Area/Code Entertainment and Newtoy, acquiring the rights to publish the popular iOS titles Drop7 and Words With Friends.

Zynga's Dream Heights is available for download from the App Store in Canada. A worldwide release date has not yet been announced.
