iPhone publisher ngmoco has announced that its MazeFinger game has been downloaded more than a million times in just three weeks on the App Store.

Admittedly, it's free, so that doesn't mean ngmoco's execs can order in the speedboat catalogues just yet. But it's an impressive start for the company.

"The success of both MazeFinger and Topple has blown us away," says CEO Neil Young.

"To think that over 50 million mazes have been completed in MazeFinger is a staggeringly cool number and speaks to a level of engagement that distinguishes our fun, micro priced fast apps."

(Have all million downloaders completed the game? Lumme.)

ngmoco has already released one update for the game, allowing players to save their high scores, and resume games if interrupted by a phone call.
