Picked this up yesterday, and already found 2 bugs in single player mode:

1) When capturing dice, once you capture the first one, it does not allow you to review the card, then capture the second die. It merely captures it.

2) You can spend Quiddity that you don't have, I think this only happens on second or later capture, but I could be wrong. It doesn't seem to be recalculating Quiddity correctly.

Outside of that, the app seems pretty fun.

And the Wilds registered as empty before they actually were (not a single Dragon die had been purchased).

I started a thread about the game in another forum. As far as the Wilds being empty it's not ALL the Wilds that have to be empty.

So the Dragon could have all the dice still on its card but if 4 other Creatures were empty the game ends. I think the tutorial needs to be a little more fleshed out and the help definitely needs information on the different ways the game can end.

And I keep seeing people talking about being able to capture things that cost more than they have but I have yet to actually see it in my game and I've played probably 50 games. So it must happen under certain circumstances or something.
