Crazy Climber is an action-packed adventure game where you play as a climber, trying to reach the rooftop of a series of buildings by catching a helicopter that awaits at the top. As you climb, you must navigate through windows that open and close simultaneously, while avoiding various obstacles such as bald-headed guys hurling objects, pesky condors dropping eggs, falling steel girders, electrical signs with live wires, and more.
The game requires skill and strategy to overcome these hazards and continue climbing. If you fall to your death, another climber will replace you at the same location, allowing you to try again from a new starting point. The game features recognizable musical themes that announce each hazard, making it easier to prepare for the next challenge.
The gameplay also includes bonus scores awarded after getting carried off by the helicopter, with the score decreasing over time unless you can catch "The Lucky Balloon", which can lift you up and raise your score. With three climbers available initially, you'll be able to scale the buildings faster, but don't forget that you'll earn an extra climber every 30,000 points!
