×Lost.

×Each style will have three moods: ambient, attack, puzzle. A mood will specify one or more filenames of songs to play. If multiple songs are specified then the songs selected to play will go in sequence. By default, mood will be "ambient" until the player enters an unconquered room. Some kind of analysis will be performed on entry to determine if mood should change to "attack" or "puzzle" mood. A rule like "if there are more than 50 monsters in the room, use attack mood, else use puzzle mood" can be used, but you want to account for things like maybe the room begins with 10 roach queens, and they will shortly turn the room into a slashfest.

×The new pit tiles go 5 squares deep.
