View my base game review here.

• Extremely cool new puzzle mechanic with lots of variation based around the flashlight. They continually innovate on this mechanic and play with it in interesting, unexpected ways
  
• Planning ahead is heavily encouraged, even more than the base game, with the added gimmick of the ring world
  
• The way you discover the DLC is really neat and feels natural within the rest of the world
  
• The new untranslatable language is a nice changeup
  
• Other great things about Outer Wilds generally apply here. Not as much of a "wow" factor compared to the base game but things are still interesting and impressive.
  
• The game takes it up a notch on the spooky/creepy factor which is much appreciated, until...

The last quarter of the DLC introduces a stealth horror section, but does it in all the wrong ways. This ruined my experience.

• The enemies operate based off light; they can't hear (there is nothing that indicates this is the case; in fact, environmental hints and visual design dictate that they CAN hear)
  
• If enemies spot you, they immediately aggro and track you perfectly unless you break line of sight.
  
• To avoid being spot, you need to conceal your lamp. Concealing your lamp puts you in COMPLETE darkness; you can't see anything.
  
• You need to be able to navigate in complete darkness. This requires map memorization. Two out of three areas are incredibly complex.
  
• The enemies will ALSO sit in complete darkness until you alert them. You can easily bump into an enemy since it blocks a choke point.

In order to get past an enemy, you need to know where it is, have memorized the map layout, then bait it one way, go behind cover to break line of sight, then quickly flank them in total darkness. Time still ticks while you're in this dream world (because the developers are sadists here) so each run costs precious time until you have to spawn on Timber Hearth, get in your ship, fly to The Stranger, get inside, get on a boat to which location you need to get to, find an artifact, then get to a campfire and sleep so you can try again.
This process is agonizing and quickly made my whole experience of the DLC sour. I had put in 5.5 hours of work to get to that point and I felt I had to stop because I wasn't having fun at all.

• You don't have a ship log easily available in the DLC so you need to memorize any codes, paths, locations, etc. This is INCREDIBLY annoying, esp because the sequences you need them for are pretty complex
  
• DLC is extremely isolated in its own part of the map so every time you have to start at Timber Hearth, you have to immediately travel there; it's a complete waste of time for no reason
  
• Existing issues/bugs with Outer Wilds still occur

Echoes of the Eye is a good DLC up until it gets ruined with a horrible forced stealth horror section near the end. The developers fail to take cues from existing stealth horror games and design a system that is so genuinely unfun it stopped me from playing. I really wanted to like this DLC since the base game is one of the best indie titles of all time, but regrettably the stealth horror section in the DLC is so bad it destroys the experience for me. Do not buy.
