'Run Roo Run' available now on iOS, from Scribblenauts dev

Description

Run Roo Run is an "auto-run" game in which you tap to jump, sort of like Canabalt -- but set in a series of pre-designed, increasingly complex levels instead of a never-ending randomly generated world. The game features a set of 420 levels divided into chapters, each introducing a new element, like double-jump items, fans, retracting spikes, and crumbling aerial platforms. Each jump is accompanied by the placement of an arrow, allowing the player to see exactly where he or she took off from, in order to correct fatal errors in the next attempt.
