Dungeon crawlers, my other nemesis. The difficulty of this one is not understated - not for the commands, as it uses the basics cardinal directions, attack, examine, and take; or the size of it, as it is pretty small; but for the combat part. It is quite difficult, and you might need the RNG God on your side (or maybe undo-scum). There is an order to which the rooms should be visited to avoid getting hit by the monster guarding it (and it is possible to avoid killing some of them to win). I've died A LOT and not managed to pick up more than 40 gold pieces.
Though it is hard, the game takes a more humorous approach in its writing. You are some sort of adventurer wanting to steal all the gold of a vampire in that dungeon. and won't back out until you reach it (or die). It's silly, but fun!
I kinda wish you could include more images in parser, because that cover is pretty dope.
