Just thought I'd post this bug I found but never got
around to e-mailing you. :) If you run the game on a PC
with no sound card installed and thus no sound driver,
the game only stays up for a few seconds. Presumably,
once you do something to trigger a sound it tries to play
it and some kind of overflow occurs.
Anyway, it should probably be handled by the game
library you are using (I forget the name), but you might
want to have the option to turn off sound if a sound
device is not detected.
