Waker is a puzzle platformer in which the player has to build their own platforms to reach the goal. To create a new path, you must first reach a magical orb and grab it with the action button. You can then control how the platform is to be drawn by moving the creature around the screen.

There are three worlds to explore in total, each with their own subset of levels. An abstract version of the same game called Woosh was also released together with Waker, and you can find some of the other Summer 2009 Gambit Prototypes from this page.
