A very basic and simple map editor, that allows playfields of pretty much any size you like and can handle tile sizes 16x16, 32x32, 64x64. It also allows an unlimited number of layers (well, until you run out of memory/patience, really).
File includes a player that you can use independently of the editor.
It's not meant to be advanced or anything clever, but it works (which can't be said for PB maps at the moment). I'll post updates to the editor and the player as I work on them, but for now.
BTW. The accompanying tiles are 32x32 and the demo file needs to be run in 32x32 mode. Also thanks to Henrik Spettrup for the tileset.
Be aware - you can't currently add layers once in the editor!!
