Coming this thursday: http://i.joystiq.com/2012/01/10/5th-cell-introduces-run-roo-run-its-new-weekly-ios-platformer/ Run Roo Run is an "auto-run" game in which you tap to jump, sort of like Canabalt -- but set in a series of predesigned, increasingly complex levels instead of a never-ending randomly generated world. This is the "micro" aspect of the "micro-platformer." "That means every level, from start to finish, is just a single screen wide," creative director Jeremiah Slaczka told Joystiq. "Typically, auto-runners don't have levels, you just travel as far as you can until you die." Those 420 levels will be augmented by a weekly release of 10 levels, for free -- a delivery that "won't require a product update," Slaczka noted.
