This is brilliant and might just be the thing to make my prediction come true. With your permission I am going to port the code to Arduino and run (sort-of) Doom on my video display shield.
it is just a cheesy game, I had the idea to use still frame images run in a loop and use system("cls"); to give the illusion of 3d by clearing each frame before the next, like a flip book. The rest is just random dungeon generator with random enemy encounters, leveling and eventual dragon slaying when all the treasures are found. Far from finished but it is playable, just download and run the zipped .exe file.
Its not so much the gamplay but the how you do it (ascii) nice old school
