Arrow keys to move, just don't press more than one at a time
The other day I was thinking of "ASCII graphics" games like Dwarf Fortress and A Dark Room, when suddenly the idea for this little experiment struck me. While I did set work to it immediately, I didn't properly begin 'til the next morning, where I finished it in about 20 minutes. Though it'd take a while (there has to be a better way to code this), I do believe it'd be possible to make a very basic game using this system. I may try to later.
