Hell: A Comedy of Errors

In this game, you pick your gender and characteristics and start building your own little corner of hell.

You have a catalog that you can buy stuff from, including new room types (represented by gemstones). You dig out rooms in any direction you want, then drop a soul in it. You get 1-3 points for each soul you place in a room. To get more points, you might have to buy a torture device or set a demon in charge of the person.

I went up levels pretty quickly, but eventually stalled. Many reviewers (and me) have come to the conclusion that the game is unfinished, and you can't actually play it in the intended way. This same author went on to wrote several more massive games with brilliant systems that ended up not being implemented.
