It seems very interesting as a more 'party game' type RPG that non-gamers can get into. I can already see some possiblities for the Jenga mechanic and I haven't even read the book.

One in particular is forcing the players to decide how much time they want to spend doing something. Say one of the characters is a Professor and he needs to research a way to banish an eldritch horror as said horror gets closer and closer to its goals. Every pull he makes represents an hour of research time and gives him a 'pip' towards defeating it, but it also risks bringing the tower down which means he dug too deep for too long and the amount of forbidden knowledge made him insane. After that, all he can do is babble incoherently and the other players will have to try and discern from his mad ramblings what to do.

While he is researching, the other players could be pulling as well to delay the horror as best they can, possibly causing one of their characters death at the price of giving him time to finish his research. I can even see a player sacrificing himself in a heroic action (say by charging the horror with a bomb to force it to reform) by intentionally pulling the wrong block to force the tower to fall on himself. The possibilities are intriguing...
