Masterpiece; 10/10.

It's a near-flawless (and respectfully intelligent) adventure game - a cerebral and heartwarming experience all in one. Possesses one of the most fantastically interesting mysteries among all the games I've ever played.

If you want to unearth everything that this gem of a game has to offer, all you need is a patient and curious mind - the game does not hold your hand or give you quest markers, which makes exploration feel exceedingly rewarding.

However, if you carelessly look up spoilers for this game your experience will permanently be tarnished. Here, knowledge is everything.
