I love when games like this come along that just reaffirm my belief in the potential of games to be art in a way that is different to any other medium. This game explores concepts about the end of the universe in a mature and interesting way while managing a level of non-linearity and natural, hands-off player discovery while still managing to be fun! Such a great culmination of good design tendencies.

The way this game tricks you into thinking you can save the universe, stop the timeloop, stop the sun from going supernova, only to pull the curtain back and reveal that its entirely beyond your control is essentially one of the greatest gameplay-story harmonies ever created. It conveys the fatalistic, fact-of-the-matter aspect about the universe ending through gameplay without devolving into borrowing thematic elements from other artistic mediums (i.e movie-like cutscenes)

Definitely consider it a masterpiece and it captures a lot of what I want games to be like.
