The idea of an uncontrollable drunken dungeoneer is great, but I'm having a hard time understanding how to play the game. There are three types of potions I can give and I guess that the drunkard has to go to the exit. However, I don't know what all of the symbols on the map represent, and how they relate to the three potions.
My advice would be to start the player off in a couple of handcrafted levels, in which you teach the basics of the game to the player. Start with an empty dungeon with just the exit and the sober potion available. Then expand upon that in the follow levels.
