Got this done using less than a weeks worth of time. The Atari 2600 is a very basic system so only basic Rogue-like elements are in place.
* Dungeons floors are procedurally generated.
* Delve down 5 floors and retrieve and artifact. Bring it back to first floor.
I did deviate from permadeath and instead opted to warp the player to a near pitch black dungeon floor.
