I loved it and also found it surprisingly difficult in places. I think the use of mixed media is brilliant, like the various flavors of video clips and music you stumble across. A couple boss battles were very challenging. One in particular, but you can finish the main storyline without beating it.

The section of the Oldest House that opens up into a vast maze of hallways is totally epic, IMO. The soundtrack gets metal in a cinematic way right there (Old Gods of Asgard, I think, from Alan Wake? Plus Porcupine Tree!)

I enjoyed the dark and yet whimsical vibe, if you couldn’t tell.
