The Dice Tower review of this game is very helpful to understanding what this game is about, and that it probably has a rather limited intended audience (of which I'm a member).
BE FOREWARNED, HOWEVER! Purchasing a "hard copy" of the cards only gets you the cards (and the box to store them in, if you wish) -- IT DOES NOT INCLUDE A HARD COPY OF THE RULES! Generally if I purchase a game, I expect the rules to the game to come with said game, in the same form (digital or hard copy) as the form I purchased, and I find it bad form that that is not the case here, and that it should be up to a customer's review to make that clear. The "Alternate Preview" link provides the full rules, so one simply needs to download that PDF and print it oneself, but I really feel that should be explicitly pointed out. Caveat emptor! Aside from this concern, I would give the game a 5 star rating -- with the understanding that this IS a game for those who enjoy formal logic, and perhaps had a little introduction to that in school through math class, computer programming, or a class explicitly in formal logic.
