Crazy Kong is a fairly standard version of a popular arcade game. You must climb the ladders, collecting diamonds and jumping over various objects coming at you, in order to get to the top of the screen.
Unfortunately there is a slight bug in the program: when jumping over objects you may lose a life even though you do not hit anything.
The keyboard controls are more of a hindrance than a help, so you need to be good at finger gymnastics to use them. I would recommend a good quality joystick for playing the game.
Good use is made of the sound facilities, but better use could be made of the graphics.
The cassette comes with very brief instructions. You must work out the game for yourself if you have never played it before in the arcades.
The program is recorded slightly differently on both sides of the cassette, which should help you to load the game correctly.
At first, Crazy Kong is tedious and difficult to play. But stick with it - it improved with practice.
