Year Walk is best described as a sort of stylistic adventure horror game. It's not really a hidden object game, but more focused on atmosphere and puzzles. The story of Year Walk is that you play as a man named Daniel, who lives deep in the woods. You are about to perform something known as a Year Walk, which is an old Scandinavian legend to starve before the midnight of New Years and wander into the forest and night to seek a glimpse of the future. However, there are trials, and strange beings that are said will try to apprehend you, as the very act of Year Walking breaks the two truths of our world, time and space. As you play you have to overcome these trials, explore the deep and progressively strange and unsettling woods, and over it all maybe piece together why Daniel is so concerned about the future to risk his life.
The atmosphere of the game is great. It's more unsettling, surreal, and strange than scary, but I had a constant uneasy feeling and yet fascination to events as they transpired around me. Everything dips into legends and myths from Swedish and Finnish tales, with a helpful encyclopedia if you're interested in knowing more of the origin of things around you. The whole atmosphere is backed by a fantastic soundtrack that, like the game, is appropriately off-kilter.
Year Walk strikes me as one of those games that sticks with you long after you beat it. The story isn't entirely surprising in how it plays out, but it's executed very well, and the details are a lot stranger and help make the whole situation far stranger than what actually happens. It's sort of like a classic folk-story in that what happens is somewhat predictable if you have any experience with stories of a similar kin, but that's not what makes the story interesting, it's how it's told and how everything comes to that natural conclusion. And Year Walk has a lot of depth, things to look into, and intriguing mysteries that stay in the mind long after you find out what ultimately happens.
Gameplay is pretty simplistic. You move left and right along a first-person 2D plane, and occasionally can walk forward or backward to another 2D plane. You interact with objects, and solve puzzles. The game isn't stylized like many other adventure games, with hidden item to find, as what you can and cannot do and interact with is very visible and clear, but some of the puzzles are a bit tricky. My tip is to sometimes think outside of the box. Most of the answers are often more obvious than they may seem at first, none are too challenging, but some aren't pushovers either. I also heavily suggest you keep a notebook and pen handy, it helped me a lot.
It's a game with great atmosphere, an interesting experience that'll last you about two hours, and for many I'd imagine an interesting introduction to Scandinavian myths and folklore. If you have an interest in atmospheric horror experiences, folk stories, or games with a surrealistic edge, I'd definitely give it a recommendation.
