Pretty lame update, although it's pretty late here and I wanted to post something before I go to bed. Basically these are supposed to be "rocky" caves that can go with the purple ground tiles. Also freed up a bit of space so people can easily add new tiles.

Will post more stuff tommorow.

EDIT: Fixed a small tiling problem with the mountains.
EDIT2: Blah, just realised I accidentally messed up the postitions of some of the tiles. I feel like such a loser now. ;_; This has been fixed.

If you downloaded this image and made new tiles on it, please redownload it and add the tiles onto this.
