I played through this on my first ever livestream a few months back. I was able to beat this in a single sitting, so it's something you'll get your money's worth (vs a AAA game you never experience most of without a disproportionate time investment).
You're thrown into the story without much instruction and you're not given any clues outside of those presented as part of the dialog. A couple of the puzzles hung me up but not too bad.
Good story and the voice acting is great.
