Gridmap is a moderately simple map loader. It will load tiled maps created with Tiled. It returns a display group with each layer inside it. I wrote this very quickly; if you find a problem, just post on this page. Gridmap is not extremely sophisticated - no extras, just loading maps. But, I hope it will help someone, as it has helped me. I have also only tried it with orthogonal maps - no isometric ones. Loading isometric maps is not guaranteed.
Feel free to edit it in any way you want to.
Tiles are each individual sprites.
