10/10 : The Best Game Ever. DO NOT GET SPOILED AND PLAY IT !
85/100 : Metacritic

+ The Gameplay design : Only the knowledge of the player will get him to move foreward, everything is accessible from the beginning. There is an euphory in understanding key points of the story and puting an hypothesis into test gameplay-wise in order to advance in the game. It also has a great middle ground between fun and scientific fidelity.
+ Amazing story, music, art direction
+ Memorable solar system, each planet beeing handcrafted and well designed
