How to climb

• Q grabs or lets go with the left hand, E with the right (tap once).
• Not holding anything: W / S move the hands up and down, A / D walk (or move the hands in the air).
• Holding a rock: W pulls Gurt up, S lowers him, A / D move the free hand sideways.
• Both hands holding: W A S D moves Gurt's body.
• The mouse still works too: move it to move the hands, hold left or right click to grab.
• Esc frees the mouse.
