A Dense jungle tileset Tile Set for autotiles, by Edaz released under the Creative Commons atribution-share-a-like 4.0 license

Tiles are 16 by 16 pixels each.

If you want to change the layout of the tileset, you can rebuild the source image(s) into a new tileset using TileSetter, a free tool by Led. (NOTE: the tileset.png file is already made into a tileset, you do not need to build it)
