Progress from version to version is fairly slow (sometimes a couple of years will elapse in silence between releases), but every change in the game is debugged extensively and thought out to its fullest extent. The result? A fascinating exploration of possibilities.

Some examples: Eat a floating eye corpse and you'll get ESP, which will allow you to see enemies anywhere on the map, but only while blinded. To take advantage of it, you may want to drink a potion of blindness, or preferably, find and wear a blindfold. Of course, while blindfolded, even with ESP you won't be able to see inanimate objects on the floor -- when you find piles of items, your character will have to "feel" for them. Oh, and you won't be able to read scrolls. Whoops! In that pile of items you just felt is a cockatrice corpse -- fortunately you were wearing gloves, otherwise you would've been turned to stone just by touching it. But now, blind and protected, you can pick up the cockatrice corpse and use it to attack monsters -- now your enemies will turn to stone when you strike them! Unfortunately, their inventory turns to stone as well. Hey, no problem -- you've got a pick-axe, so you can chisel open their statues to yield a pile of rocks and any of their old possessions. Sadly, thanks to the blindfold, you can't see a nearby pit and tumble inside. Too bad you were holding the cockatrice corpse -- it landed on top of you and turned you to stone. Yet Another Stupid Death, and another reason to cry out in anguish because they think of everything!
