Tanagra is a prototype mixed-initiative level design tool for 2D platformers. It allows a human and a computer to work together to produce a fully playable level. At the heart of Tanagra is a reactive level generator, which responds in realtime to any changes made by the human designer. Tanagra supports editing both the geometry that appears in the level, and directly manipulating the pacing of the level through a timeline.
