Cool indie game. Decent amount of hours/content for the price. 6 mountains with occasional branching routes that give a replay value. To complete all routes in the game it will take around 12h. It also has an optional no oxygen stat for the time it took one to climb to the top so that can be some extra replay value too.

Gameplay is nice, it's a mountaineering simulator where every action you make (walking, jumping, eating) costs you time(of day/night), stamina and other stats. So one must manage everything and keep track of things. Jumping to pull yourself up can often be clunky , other than that all is ok. Pay attention to the tutorials as they will explain some mandatory skills. Also make sure to re-climb previous mountains to build up some money as you will need it for better/more gear. Trying alternate paths is a good option here.

Crevasse crossing was both fun and scary. And there are plenty of different weather conditions too. But there is nothing better than when night catches up with you and your headlamp runs out of batteries while you happen to be in the middle of a near bottomless crevasse cross on a ladder. Or when one randomly opens beneath your feet as your forgot to test the ground first.

I wish that they added Broad Peak and Annapurna as they originally planned in the demo. But fun game nevertheless.
