Insurmountable

Developer ByteRockers games present a unique twist on the roguelike genre with the mountain-climbing Insurmountable.

Play as one of three mountain climbers as you try to climb to the top. Along the way, search crates, caves, and ruins for supplies, as you will need them to reach the summit. Grow your skills, become stronger, and be able to fight off the dangers of the mountain, from wild beasts to harsh weather. But be careful, as when you die, you die permanently. With three mountains to conquer, each of them procedurally generated, you need to push yourself to the limit to survive. 

Insurmountable is available for the PC and Linux.
