Hi Kristian,

The game is currently pure C and C++.  As for libraries, I currently use 
xerces (XML), curses (UI), Google Test, and boost/stl.  The game itself 
is currently in a playable state - the player can win or lose, there's a 
generated world to explore, etc., though it's currently pretty bare.

My plan is to start with reasonably small scope, and use Scheme for the 
quest logic.  I'd like to have a number of optional side quests beyond 
the basic roguelike "dive to the bottom of the dungeon".  I could do 
this in C++, but I see an opportunity to work in my favourite 
programming language, so I'm going to take it. :)

Much too late for that, I'm afraid!  The game itself is currently just 
under 2 MB of code, resource strings, and configuration details.  I'm 
quite happy with its current state.  I'd love to try Scheme as the main 
language for a game, but this project's much too far in for that.
