You better find this useful in testing the tileset and what may be needed, since I wasn't in good coding shape and wasted an endless amount of time on debugging the tileset slicing script. I used Blur's image as source image since no-one after him put in a full image. I'm not going to compile them myself. Also, collaboration features are turned off so don't bother with that.

(this tileset can be incredibly hard to use btw because of the main tiles, I notice.. try easily putting in platform ends for example. also, I find the nonseperation of cave tiles/ground tiles rather ambigious)

EDIT:

What is background, what is ground?
