I've had this on my wishlist for a while, and I doubt the price is going to drop back much farther than it just did, but some of the early reviews mentioned severe bugginess. Has that changed appreciably.

In short: yes.

Most (if not all) bugs related to quests should be fixed now (I haven't had any issues with a version I tried a while back - and it's been updated a few more times since then).

Additionally, they've made significant modifications related to balance, so the game should actually be somewhat challenging if you crank the difficulty up. I say "should" because I haven't played it since some versions ago.

Bit late, but for anyone who is wondering;

I just played through the first chapter and encoutered no bugs.
