Game & Watch style Donkey Kong. This unit comprised 2 screens, and guided mario to the top, to leap for the crane hook and dismantle kong's platform.
Select from Game A or B. A= easier, and no girders. B= harder with girders. Use arrow keys and shift to jump. Did you got that?
Use the lever by pushing left while next to it, to active the crane hook.
At the top, you must jump (shift key), when the hook has swung at its leftmost position to grab hold of it.
Once all 4 hooks are gone, Kong will fall. The faster you go, the more score you will get each time. Bonus life every 300 pts.
