Klifur is a physics-based 2D bouldering game. Climb through over 30 hand-crafted routes. Each one is a small problem to solve with no single solution, just better ones. Take your time, try different sequences, and work toward cleaner, more efficient runs. Earn badges by optimizing for move efficiency, time, and eliminating holds. Make your own routes with the built in level editor! Share them with friends by sending them the route code.
