Khadgar42: I got the second artefact and now enemies are getting tougher and tougher, I like the difficulty as it was before, though I admit the first two or three bosses were too easy, but I'll grant them the tutorial bonus.
I'm on the tenth boss run now, and so far only died twice ( and at least one of those deaths was rather cheap, because of a particular nasty card, not regular combat ) so difficulty seems just right. Combat is exciting, and I've had many close calls, but as long as you keep moving and use your equipment/special skills wisely you can usually emerge victorious.
I'm kind of hoping and expecting that the game isn't over after the 12 main boss monsters are down. Since you only take on the Jack, Queen and King of each suit during the main storyline, do you think there's "Aces", too? Still haven't tried Endless Mode, either. And for what it's worth, the late game dungeons are much tougher and longer than the first half of the game.
