Found it much less engaging and charming than the main game. There's no sense of wonder and exploration, you're basically just solving one isolated puzzle level instead of piecing together the mystery of an entire game world.

The light-based mechanics are very nice, and the planet is a cool addition to the roster, and obviously much bigger than all the main ones, but the things that made me look past the more annoying aspects of Outer Wilds are just not there anymore. Space plays virtually no role in the DLC, you're just booking it to the same place over and over again. The mystery seemed small and inconsequential compared to the multiple intertwined mysteries of the main game.

The annoying aspects themselves, however, are still very much there. The runback in the main game could feel brutal, but you just couldn't wait to explore more of the story, so you just bite the bullet and retrace your steps for the tenth time. In the DLC the runback is many times more exhausting (go into the DLC world, swim to the location you need, enter the subworld there, runback to the place you need there), and there's just not that much that compelled me to come back.

Might return to it later, but for now it even began to tarnish the good memories I had of the main game, which is just unacceptable.
