This is a fairly unique "Double Ender" cartridge that contained two separate games. You simply removed and reinserted the cartridge "backwards" to get to the other game. This compilation included:
Spike's Peak is an action game where you need to climb to the top of a mountain! Gameplay takes place on five different screens. The first screen shows you approaching the mountain; you begin here each time you start a game or lose a life. All you need to do is walk up the path to begin the stage you've reached so far. Flags by the path indicate how many lives you have left. The next screen is a zig zag path through meadows at the base of the mountain. Beware of the deadly bears and eagles here! Along the path are several caves which you can hide in when a bear or eagle appears (you can also jump over bears). The caves are cold, however, and you have a limited amount of time to hide before freezing to death. Make it to the top of the path, and you begin the next screen. Here you climb up a rocky ledge. Boulders and falling pieces of rock constantly appear and can knock you back down the screen. Next is the icy cap of the mountain. Climb up to the top without being knocked down by avalanches or getting caught by the abominable snowman. The last screen takes place at the mountain summit where you need to climb to the top and plant a flag before freezing! Complete all of these screens and you win the game. There are four different difficulty levels available.
Your friend is trapped inside Ghost Manor! There are five different screens you need to get past before you can rescue your friend from the top floor of the manor. The game begins in the graveyard outside the manor; here you play tag with a friendly rainbow ghost or skeleton which will supply you with spears you can fire at enemies. In the second screen, you approach the guarded entrance of the manor. Using the spears you collected, you need to shoot all of the enemies blocking the entrance. The third and fourth screens take place inside the manor; each floor has a set of stairs as well as several treasures and crosses which can be collected. There is a moving wall on each of these floors which is deadly to the touch, so be careful! The final screen is the top floor of the manor where your friend is being held captive. Dracula guards this floor, and using the crosses you collected earlier you need to repel him into a prison and free your friend. To make the game more challenging, there is a time limit; you must complete all of this in four minutes or less! You can play the game as either a boy or a girl, and four different skill levels are available.
