First off this game pushes the limits of what can be actually called a game. There is no game here. There is no fun, no puzzles, no action, no thing. It is as close to the description of a walking simulator as you can get. Having said that this is easily my most favourite digital "thing" I've "experienced" for a very long time.
You explore and island but really even this is only an illusion, any choice you make in direction essentially leads to a dead end or loops around to where you started. There isn't really a story, only snippets of letters that the narrator in a random order reads to you.
What you take from the experience is what you put into it. Listen to what you find out, analyse the smallest details of the island and you'll draw your own conclusions on just what the Hell is going on. So little is given to you as fact that you never *really* know who you even are.
My only advice is approach it with an open mind, make sure you've got 2 to 3 uninterrupted hours (tops) to spare, snuggle in warm with you hot drink and cosy blanket of choice and don't rush anything - take your time to notice how immensely beautiful the game world is. I lost count how many times I just stood and looked out over the landscape.
I now have an uncontrollable urge to visit a Scottish island on a rainy and overcast day.
