@egordorichev, Hey thanks! Great tile set. I'm kind of an aseprite noob, what do the blue outlines in the .ase file mean?
These wont be visible, if you export the whole file to png or whatever, these are specific to aseprite region markings called slices. You can modify or view their names with the slice tool ( C key by default).
Thanks! It looks like you can export the entire thing as a spritesheet too using slices.
