Insurmountable is a roguelike adventure game with permadeath mechanics in which the player is tasked with traversing huge mountains. The procedurally generated environment makes every climbing session different. If a mountaineer is to survive, you must constantly make sure that his vital signs do not reach critical values. An additional difficulty in completing this task is the dynamic weather system, changes in conditions during the day and night, and a lot of randomly generated events, the outcome of which you can never predict. Your decisions matter... each of them. Each one can be your last. Choose from three characters with different skills and biographies to start climbing your first peak. Scour chests, caves, and ancient ruins for equipment left behind by previous daredevils. You will need it, because you have to do your best on the first climb. Don't worry, though. As time goes by, you will gain experience and strength. Use an advanced skill system and decide what strengths your mountaineer should have. Through three mysterious scenarios, you'll traverse deadly crevasses, encounter menacing animals, as well as sinister and friendly characters who won't always be human. Each of the decisions you make will have an impact on the development of events.
