This is the very key to the whole game, and where the game shines: there are no skills to earn, or items to find, to progress; even the melody abilities (which you will have to discover on your own) act more as utilities (e.g. fast travel); knowledge of the environment and its creatures is really all you need, and the gameplay possibilities explode as you learn more about them.

And, as a puzzle game, it is exquisitely designed and a real joy to play, with beautiful graphics, delightful music and sounds, and of course, masterfully crafted puzzles that naturally escalate in difficulty as you learn to use your seemingly limited abilities to interact with various creatures and control the environment in increasingly more complex - and often surprising - ways.

Also the puzzle difficulty was just right for me; at first glance a puzzle seemed easy, then it felt impossible, and just as you start to get frustrated and feel like searching for a walkthrough, you figure it out.

The soundtrack is delightfully serene, arguably cute, and whilst it won't be winning any awards, the calming musical nature will have you chirping along, and there's something appeasing about the aesthetic of a song not trying too hard.
