Music is great, and the gameplay feels solid. I was originally interested in trying this out after watching the NoClip documentary & hearing about how the game tries to handle death. I feel the documentary oversold this aspect of the game -- the game does vaguely talk about death, but if you're interested in this kind of subject matter, A Mortician's Tale is much more likely to be up your alley.

I also don't feel like the secret ending of the game was worth the time I spent hunting down all of the collectibles.
