I would absolutely recommend this game.

It's relaxing and casual, with absolutely stunning scenery to get lost in and explore, but in spite of zero text or dialogue through the game has the ability to hit you squarely in the feels.
Had I known this, I might have waited longer to play this, but I am also glad I didn't. Cathartic and then some.

I'm steering away from the story, because it's as much or as little as you want to make of it, though you will get more out of it if you don't just rush to solve the puzzles. This game proves though that communication is about more than words. The soundtrack is beautifully composed - I've left it on while I had a nap...

It's not a perfect game - in spite of regular save points, exiting the game will sometimes skip you back to the start of a chapter, which can be frustrating depending on the puzzles - likewise if you explore a little too much and get stuck (guilty a couple of times!) your only option is to exit and risk losing progress.
This has meant I've left myself on away rather than turning off at times, which isn't always ideal.

I really want there to be more, but the game is complete in terms of the story - I'd love to see another game based on a different myth or idea though.

And I would play with some tissues to hand - especially if you have a soul at all!! (I spent the end of chapter seven onwards playing whilst ugly crying... >.>)
