Super Mario Galaxy has that one very memorable mountain covered with purple coins.

And Getting Over It With Bennett Foddy comes to mind, though I'm not much inclined to try it. It is "aimed towards 'a certain kind of person, to hurt them.'"

For "jumping from high places", there's AaAaAA!!! - A Reckless Disregard for Gravity and its sequel.

And there's https://store.steampowered.com/app/313340/Mountain/ , but that's a different kind of high mountain.
