Very cool concept, loved the graphics and the humor!
It took me a bit to figure out the values but I got them, I ran out of time to try all the cards but I think I figured out one :-)
A WebGL build would have been nice, I bookmarked the game on Monday but it took me a couple of days to reinstall my old computer because I'm not running unknown software on my real machine ;-)
It is one of my favorites, it really got my puzzle brain going! A little caveat would be to shorten the roll time because it felt a bit long to me but very good job!
