Have you tried Rogue?

Rogue - A very old game programmed in the 1980s. It is essentially a dungeon crawler stripped down to the bare bones of just the gameplay itself. You use a DOS screen to move your character around(a smiley face) and hit monsters by running into them. So far, I've yet to get past level 12, as this game mimics being literally in a dungeon. Sometimes, there seems to be no way out and you'll have to search all over the cavern you are in to find an escape route, and there is a slight possibility that you may die from starvation, though I have yet to do so. The game can be very unreasonable at times, throwing a Troll at you when you're just a level 5 character and thus, you die. Sometimes you have 30 hit points and still get killed by a miserable snake. So yeah, download it (0.1mb)
