I Highly reccomend this game. This is a game that solving and progressing through is reward enough, but also gives you creative freedom to explore on your own. It's the perfect blend of being forced to progress each puzzle linearly, as in Portal, and having total control of where you go and what order you interact with your surroundings.

On top of that the game remains fresh and stimulating the entire time. Puzzle aspects are reused, but there are no two areas in the game alike and while you can get stuck in an area I felt like the puzzles were very intuitive and neither drole nor trivial.

10/10, this is without doubt the best puzzle game I have played, and ranks really high among top games I have played.
