Diabaig is a traditional turn-based ASCII roguelike where you are never more than a few mistakes away from death. Choose a starting class, find powerful items, and learn new spells and techniques to face increasingly dangerous adversity. You will discover many floors with rooms filled with unique creatures, magic scrolls, unknown potions and mighty weapons. Use everything at your disposal to survive as long as possible and defeat the dragon, but remember to keep enough spare for the return journey.

The Tombs of Asciiroth

"The Tombs of Asciiroth is a free, open source game you can play right now in your browser. It has arcade, puzzle and exploration-style game play in an extensive world of font-based abstraction. If it looks a little old school, it's only because I've been trying to make this game since 1980. But other things kept getting in the way. Hope you have some fun with it. "
