A great addition to a masterpiece, brimming with new ideas and content of almost a sequel while finding a fascinating spot in the Outer Wilds lore where you didn't think anything was necessary before but are glad that they decided to tell this story. As two packages Echoes of the Eye feels more mechanical, almost Escape Room-like with new knowledge mainly pertaining and pointing to secrets used to progress, while the base game fed off an archeological and explorative drive making connections along the way, which I personally found to just be more interesting for my taste in the end. They feel very distinct, which is really good since Outer Wilds felt pretty complete already.

Oh, and this is a horror game. Boy, they nailed this aspect (apart from a few overwhelming bits in the latter half) and the music, THE MUSIC. Great new tracks and fantastic remixes of iconic old tracks, almost triggering nostalgia already at this point.

This is a necessary play for everyone who liked the base game and is well worth the price, I was worried I would never be able to enjoy something 'Outer Wilds' for the first time again, so I am weirdly emotional that I still got the chance to have a new experience in this universe.
