After discovering the performance was still good while looking at landscapes from the cliff, they started to develop a game around the view. They first built the demo in a cave, before moving it onto a cliff. The Climb started development as a demo called Return to Dinosaur Island. The Climb additionally has an endless mode, that randomly generates sections for the player to climb. The player can also encounter ledges covered by rocks, which they need to brush off with the controller before grabbing it. These environments contain different hazards, from poison grips that drain your stamina, to small ledges where you have to hold the grip partway to hold on.
Each of these contains five levels which are: Easy, Medium, and Hard, alongside two bouldering maps. The game features three different environments: Bay, Canyon, and Alps. To keep holding on, the player needs to chalk their hands to maintain grip, which they can do by holding a button and shaking the controller.
If the player reaches a gap too big to the climb across, they can push off of the ledge to jump across. The player climbs using the motion controllers, moving their hands to grab the next ledge. The player starts out in a tutorial area, where they can choose what they look like and practice the game's climbing mechanics.
