So I just got this game called "Celeste" and basically you play the character Madeline who is trying to climb this mountain called "Celeste Mountain". The mountain is supposed to be a very weird place (I just got the game so not much has happened). You eventually can find this person named Theo who tells you he has a "InstaPix" (Instagram) account nameed "TheoUnderStars" and it's actually a real account that is full of art about the game. https://www.instagram.com/theounderstars/?hl=en
