Got my physical copy and "played" it the whole way in one sitting despite not being an artist at all. If you can afford to get the physical book I'd highly recommend it, the paper is excellent for even heavy handed drawers and it's just so cool to have a completed game book to show others. I knew it was going to get dark but it went into a direction I really did not expect with that darkness.
It's also unironically very good inspiration for thinking about perspective.
