Two game modes:

Rock climbing: There is only one correct path to get to the top. If you stray and make two mistakes in a row, you will be hanging by the rope a few feet lower. Remember that the time for the ascent is limited, and that the two climbers must reach the end of the route.

Ascent to Everest: You are going to climb the highest mountain in the world and that has its complications. This time you play with two roped climbers moving in parallel. Time is running against now too, and before it's over you must place your ikurriña on top of Everest.
