Canyon Climber

Canyon Climber is a cartridge game from Radio Shack that is loosely based on Donkey Kong. You have to navigate through 3 screens of opponents, etc. to get to the top of the canyon. On the first screen, you have to set dynamite charges while dodging goats, and then run to the top to blow it up with the plunger. A nice screen-shaking effect is done at that point (by switching graphics modes very rapidly). On screen 2, you must jump over arrows that are being shot at you by Indians, or you can get your own bow and shoot back. Once you get to the top of this, you go onto screen 3, where you must dodge bird droppings while jumping from cliff to cliff until you get to the top.
