So, initially, there's only one monster on the board, being that there are only 2 tiles and one has the rogue on it, stacking a bunch of monsters on there didn't seem fair.  At the beginning of the monsters' turn each round the "Game Master" roles 1d6, on a roll of 1 the GM will add a wandering monster to the board.  I've had runs through a level where none were ever added, and I've had runs where every round a new monster got added.  It can get really hard really quick.  There are 5 different monsters, each with different stats, in the game.  A good trick is to build the dungeon in a way that the monsters will move away from the stairs and you can avoid them completely.  

That's very interesting about the text on WINE.  Did it show up in the menus?
