It's Christmas Eve and poor Santa Claus can't remember where all the presents are. This means that you, as his most faithful helper, have to search for them in his network of underground caves.

In addition to finding and collecting 220 gifts, you also have to clear the place of 130 tons of snow that got in while the roof was under repair.

To make matters worse, the Society Against Enjoying Christmas is booby-trapped all over the place with kamikaze snowballs and puddles of water covered in thin ice.

Snowballs will do their best to crush you as they fall from above, while stepping on ice will mean you'll fall into the icy water below. Either way, you lose a life, and since you only have three to start with, you better watch out.

Just before you start your quest, Santa Claus appears and tells you that the magical snowmen that live in the cave will help you against the ice pools, but there is also an unpleasant side effect. He can't remember what that is, so you'll have to find out for yourself. He also mentions that snowballs can be pushed into an empty space allowing access to other areas.

At the start of the game, you will be prompted to enter the keys you want to use for left, right, up, down, and exit. The machine code and screen data are set and the game will start. If you find yourself in an impossible situation, the exit key will cause you to leave the game.

An arcade game with brilliant graphics. Let's have fun.
