About this gameFull description from Steam
MOUNTAIN 2.0 is here! Experience life as a Mountain in this relaxing nature simulation game. FEATURES - no DLC - time moves forward - things grow and things die - nature expresses itself "Welcome to an existential nightmare." - Patrick Klepek, Giant Bomb "The time I spend with Mountain feels slightly more real to me than anything else inside my computer." - Leigh Alexander, Gamasutra "Mountain upends expectations, refusing to fit into preexisting categories." - Justin Cone, Motionographer "I don’t like to talk emotions but this game genuinely is so uplifting." - Alice O'Connor, Rock Paper Shotgun "The only experience that has ever made me feel sad about a geological phenomenon." - Andrew Webster, The Verge
