I discovered this thanks to the BLM bundle a while back and have just gotten around to checking out the tileset. I immediately fell in love with it and have actually edited most of the set to work with GB Studio. As of right now, I only have a map you can walk around in, but I'm still trying to figure out what kind of game I should make with it, to be perfectly honest.
If you have any questions or concerns or just want to see what I have, I can send you a screenshot or short proof of concept video, if you'd like.
Thanks for these beautiful assets!
