Here is my last creation, a little dungeoncrawler to play solo with the help of a single poker deck. 

The idea is an ancient one I had in the 90s when I was trying to design a labyrinth generator. Eventually, I came up with the idea of using poker cards as tiles and the symbols on it representing walls and the result was a very simple game that worked quite well. 

I found the original script in my CPU, polished a bit, added some art and here you are!

Enjoy!
