This Procedural Generation Engine is everything that you need in order to start creating pseudo-randomly generated platformer levels. Only need to put the Solid blocks objects on the room and you are done. Each block will identify adyacent blocks and select sprites automatically.
You can also edit the solid sprites to make awesome effects.
Press F5 to restart room on the example room.
