Disappointed by often simplistic community made special textures and inspired by clip and trigger textures from the base game I set out to make the rest of them in the same style. This means that I used unused textures as a base and the same font.
I had to take some liberties with the font since I did not have all the letters in my sources. And for slimeskip I did not have an unused slime texture so I had to use the one from the base game.

As I said in the readme you don’t have to credit me for using these. I just wanted to share not hoard them. All the credit goes to Adrian Carmack really.
