Uhh... Just a heads up, you should probably change the commercial license from CC0.
Currently, anyone (wether they purchased the license or not) can redistribute, use without attribution, or even resell the tilemap without any consequence.
But then again... Since it's already being distributed as CC0, the genie's out of the bottle and your work is now in the public domain.
On another note, this is a really good tileset! I'm currently using it in the development of a game, and It's working really well for me!
