ALIEN8:

In certain rooms you will find a flashing object and some little men. There are 24 
of these rooms and 132 of these men called Cryonaughts. 

To activate a room you must find the object that is the same as the one that is 
flashing (like the cauldron in Knight Lore) you then drop the object on top of the 
flashing one and you have activated the room, you can tell if you are successful 
because the room goes white. You have to do this 24 times to complete the game.
