Ivy the Kiwi, the 2010 Nintendo Wii and DS puzzle-platformer from Sonic the Hedgehog-creator Yuji Naka, is available now on iOS for $2.99, a reduced launch price from its standard $4.99 price tag.

The game is a auto-running platformer — making it a natural fit for smartphones — where the player must draw vines which the game's protagonist, a flightless bird, can travel across. In addition to building ramps and bridges with the vines, the player can also use them to slingshot Ivy across the level. Check out the trailer below to get a feel for how the game controls.

The title appears to be a port of the DSiWare version of Ivy the Kiwi, which offered a shrunk-down, 50-level version of the retail game's 100-level package. A free version of the iOS app is available, but only contains a portion of the levels, as well as interstitial advertising.
