My review structure is always from bad to good, so please bear with me.
First of all, the bad:
The price is a little bit above average, for 13 pages, some people may find it relatively expansive. However, since these are just a few pages and thus only very little money, I think that the price is okay. And the product is good enough an idea so one should encourage the creator to do more of it.
The layout is functional, although having the domains table separately at the end of the book would have been nice instead of having it in the middle on a page with other text. That table is the core mechanism and constantly referenced, so having it separately would improve the ease of use for the reader.
The example does not include tools or skills or does not clarify when they are used. Not a big bad, but something that would have been useful.
There is a lengthy example of gameplay giving the reader a good impression of what the game is about.
The mechanisms are straightforward and easily memorized.
The balance/crisis variant seems highly recommendable as it adds to the unpredictability.
This title is an extremely rules-lite solitaire roleplaying game. It boils roleplaying really down to roleplaying by removing all stats and checks instead focusing on the narration and the interaction with the oracle. Many approaches to solitaire gaming focus on checks and mechanisms, so it is quite pleasant to have this game around. If you are a tactical player thrilled by finding the best solutions using your stats, this is definitely not your game. If you need oracles that spell everything out, this is also not your game as the oracle gives just general keywords that you need to interpret freely. But for those who like to focus on the narration and who enjoy being creative based on simple, small key words, this is a highly recommendable title and well worth its money.
