First of all, Rue is really cute.
Anyways, I love self-guided stories like this: searching through metadata and codecies and whatnot to reveal a bigger picture is quite a novel approach, and when done with care as seen here, it's captivating. In this game, the concept is taken further with both the player character and 'guide' themselves being part of the narrative. The puzzle box structure was immersive and it was fun to unravel (or, at times, become wrapped up in) the mysteries at the heart of the story.
Sound design, voice acting, and music are also worth shouting out. The terminal sfx made for a tactile experience, and the voice acting (so ambitious for a jam game!) was clearly tricked out with skill and precision.
If you liked 13 Sentinels: Aegis Rim, you'll find much to love here.
