Climber 5

Climber 5 is a port of an Atari 8-bit computer game that originally appeared in COMPUTE! magazine back in 1987. In Climber you play the role of a baseball player. The baseball has been hit to the upper rafters of a building under construction. Your job is to climb the ladders and retrieve the ball. Of course, there are obstacles along the way that you need to avoid or you lose a life and must start over at the bottom right corner. Once you successfully retrieve the ball, the level changes and becomes more difficult.
