Downloadable, and free to play - it's a one-player game where you, the climber, contemplate life on your way back down the mountain, or, to quote the rules:
The Mountain is a board game experience for one player. You navigate the mountain while exploring a pensive man's thoughts as he contemplates about the unknown abyss that lies exactly after the biggest accomplishment of his life.
"I've won. Now what? Three decades of ambition have led me to this moment. After what feels like an eternity of thought, I return to the edge I was so eager to climb just an hour ago and begin my descent."
It was created at a game-jam (i.e. made as a collaborative effort over a couple of days at a conference).
