Nintendo's iconic plumber has levelled up to the iPhone age, with the debut of "Super Mario Run" on iOS.

The highly-anticipated mobile game is now available on Apple's App Store in Canada and around the world (sorry Android users).

Fans were initially clamouring for the game's launch on Thursday. However, many were irked by its pricing model after it was released. The game is free to download, but Canadian users must spend $13.99 to advance beyond the introductory levels.
