The original game page (not the jam page) has some instructions in the description.
Well, thanks! ... silly me :/ ! Now I made it to the wizard, but he did really cruel things to my body parts. By any chance, do you like Dwarf Fortress ^^ ?
Dwarf Fortress is great, but I haven't played it for years. Also, the main font used in my games is based on one of the Dwarf Fortress ones.
