So this is first concept i made. its not finished yet. Before i will go on with it i want to know if it is ok to make a multilevel map. I mean would it be a problem to connect it later to others? This is probably a question to John and/or Red? I would make the side corridors (those which go to edge of the canvas) all on level 1 but there would be several levels in the middle of my dungeon. Is that ok?
