Bravo! What I’ve witnessed here is a marvellous and elegantly straightforward playable interpretation of Joseph Campbell’s monomyth.
** Do not read if you have not finished Raven Star **
From the call to adventure and the discovery of a mentor, the little raven goes to the Woods, and then the Star Mines which are both tangible embodiments of the Threshold. The temptation is posed here in Raven Star by one's own Shadow at that Treshold — as it takes place in Phantastes by George MacDonald, The Waste Land poem by T. S. Eliot, or the cave's scene with Luke and Yoda in Episode VI: "What’s in there?" "Only what you take with you."
Then, the journey stars as jump-and-run playable challenges, which I have found on a sweet spot of being finely tuned — challenging enough to stay engaging, but never frustrating. There is a clear moment of abyss and transformation. I have found it beautiful that Raven’s shadow disappears at the bottom of the cave — where the darkness is so deep that a shadow disappears — followed by a brief moment of atonement, and finally, the return to home… to have some tea.
