the frustration of dungeon without the aha moment
as one of the creators of the original "dungeon" upon which this is based, i sort of don't really think this works. in the original, the entire concept of the game was framed as a "tragedy" (as it was part of a "tragedy" competition), with a meta-tragedy being created in the discussion of the game, as a result of the twist (the game playing differently on different computers, causing misunderstandings and contention between players).
with neither the element of tragedy nor a place for discussion about the game to occur (which was what made the original dungeon a worthwhile experiment), the twist kind of just falls flat, doubly so because it's exactly the same concept and graphic wise as the original game.
basically what you get instead is a game that's got all of the frustrations of the original "dungeon," but none of the things that made people appreciate the trick afterwards -- leaving you with more or less a huge "fuck you" to your players.
