When you are in the hallway right after you beat the chess game you can find a 
panel that is sort of a different color then all the other panels on the wall. If 
you go up to it and press the square button, then you will find yourself in another 
room where you are able to get extra life points and save your game, which can prove 
to be very vital if you die.
