It feels like a DLC that Valve itself would have released for Portal 2.

The maps and puzzles are very well designed, and they even add some new mechanics to the base game.
The artstyle is gorgeous - and the updated Strata source lighting definitely helps it shine.
The soundtrack definitely has Portal 2 vibes to it.
And the writing and voice acting is quite close in tone to the original game (although I would have preferred it to be a bit darker / lonely, Portal 1 / abandoned Old Aperture style).

If you liked Portal 2 you'll definitely like this.
