ummm....
well this game has been favorited and I've been playing it steady, i've unlocked 95% of the cards and gotten most medals.
I've also done all 5 of the cave trials, but when I did the 5th one i beat it very easily in like 2 minutes. I've heard about this impossible goblin but im guessing I just blitzkreig'd it and beat it before he spawned!
absolutely amazing game tho, probably one of the best i've played
