Gameleon uses powerful tool we call the Polygon Editor to quickly create and define an explorable game map (in either a 2d or 2.5D paradigm) by overlaying polygons over a background map image. The tool wonderfully accomplishes this entirely in the browser. You upload a map image in the background (complete with textures and environmental objects etc.) and then immediately start clicking away, creating polygons that will define obstacles, walls, areas that can be traversed and so forth.
