Hello!
I am curious, did you ever plan to make a city tileset for the "villains"? Or do you have one that is specifically for villains, if yes i havent found it yet? As in a town with lots of purple and black with the "normal" things looking just a bit darker? See it as a suggestion if not =P
Don't have anything to give as an example, except maybe the witchs house tileset, but i feel like personally, that this would be rather helpful. Maybe with some purple plants etc (Very similar to those in the witches house just.... looking a bit more... evil as if corrupted by something?)
Maybe with some doorways that are more portals than anything as an option? We have snow and a lot of tohers but nothing that outright screams evil. Would be really cool.
Funnily enough we do have the dark academia pack but that looks mostly not really evil. heh
Have a good one, no matter the answer.
