I backed this on Kickstarter because of the interesting premise, expecting the final product to be on par with other indie games. I was floored by the quality! For $15 this is an amazing purchase, well worth the money. It's a fairly simple system mechanic, but the flavor is fantastic. Really encourages players to think about how to solve problems differently, rather than picking one approach and going with it over and over (as I have had happen in games sometimes). Again, it's well worth it, just a gorgeous book.
