I know I'm late, but I just bought and beat this game and wow, I am truly speechless. The visuals, the storytelling, the musical score, the companionship you form with the anonymous players that join you... Everything is amazing. In my opinion, this game is simply perfect. Perfection in it's raw form. It makes you feel so small, and evokes wonder and awe. I can't say enough about this game.
The only thing that some might see as a downside is the length. It's definitely beatable in a sitting if you power through it and don't explore at all. The length didn't bother me one bit. It felt perfect really.
Did anyone else here happen to play this game? If not, I highly recommend it. It's not very expensive at all.
