Think Diagonal!

Just a quick note. Remember that players can move diagonally. If you want a
trap blocking the parties progress, check to make sure that they can't move
diagonally around it. Example:
#O##
#O##
#TOO
####
O - corridor, # - wall, T - trap
The player can move around this trap easily by moving to the space just to
the right of it and then walking northwest. Think like a player. They're
devious. Be prepared.
