Steam now offers Getting Over It with Bennett Foddy, described as "a punishing climbing game" and an "homage to Jazzuo's 2002 B-Game classic 'Sexy Hiking'." The Windows and macOS game is quite simple for something said to be so challenging, but that's not too surprising since Bennet Foddy also designed QWOP, which made the basic act of running a near-impossible task. Here's a trailer and here's an outline:

Getting Over It with Bennett Foddy is a punishing climbing game, a homage to Jazzuo's 2002 B-Game classic 'Sexy Hiking'. You move the hammer with the mouse, and that's all there is. With practice, you'll be able to jump, swing, climb and fly. Great mysteries and a wonderful reward await the master hikers who reach the top of the mountain.

To quote Jazzuo himself: "The hiking action is very similar to way you would do it in real life, remember that and you will do well".

• Climb up an enormous mountain with nothing but a hammer and a pot.
• Listen as I make philosophical observations about the problem at hand.
• Between 2 and ∞ hours of agonizing gameplay, depending. The median time to finish for my playtesters was 5 hours, but the mean was closer to ∞.
• Lose all your progress, over and over.
• Feel new types of frustration you didn't know you were capable of.
• Magical reward awaits hikers who reach the top.
