The real mountain was in our heart.

A great game about fighting one's inner demon while scaling a mountain. Great difficulty progression with optional levels that are very hard. Overall a very good game to play in a day or two. It's also great for speedruning. Free DLC adds extra story and introduces many new gameplay mechanics.

Only reason I'm not rating higher is because it is of course pretty short and not something I think I'd be able to sink that many hours into.
