Thank you too! I initially wanted to use tiles from my roguelike pack for one of my game projects, but never got to do much with it. Then I thought it would be nice to release it for free with CC0 license, so other people can do some cool stuff with them instead. Then the Nosferatube suggested in the comments to draw some multitile creatures, so I've made this pack!
All in all, it's nice to see my art, that could've been just stuck in a folder of unfinished projects, inspire people to create some art of their own. :)
