Developed over the course of a few days, Simon Klein's Unity project is a climbing simulator that attempts to emulate and convey the extreme hardships of vertical surface scaling. A dual analog joypad is require to play, as both thumbsticks control the left and right arms respectively.

Your climber will grab on to a hold whenever a bumper button is pressed. Pushing the analog stick in any direction causes the climber to shift his or her weight, and you can also use this trick to propel yourself upwards or sideways. Some holds are harder to grip compared to others, causing you to slip if you move abruptly or attempt to reach for them from the wrong angle.

Climb is available to play at this link. The game features ten challenges to play through, and you can switch between levels at any time using a handy skip feature found at the start of each stage.
