I've started playing this recently, about 5 or 6 weeks ago, and I must say, I'm really enjoying it.
Had a lot of fun with a dwarf wyrmic, had a few goes at trying to get a decent rogue going, and enjoyed the alchemist but feels a bit 'easy' if you go for the optimal bomb-centric builds.
Started playing it 'rogue like' with only one life, but cut myself a little slack recently and started playing with more lives. Dying before level 20 regularly either way, and I really hate Urkis.
Love the variety in the character classes, it's really well designed but I really need to have an earnest crack at unlocking the brawler, which looks like a real fun class.
I suppose I should be able to take a level ten alchemist with enough cash to have a decent stint, but I've been caught out so far.
