I'm really enjoying it. I'm on level 6 or so and I still haven't encountered a single enemy I can sweep aside. Even enemies from the first couple levels can be deadly if I'm not on my toes. I love that.
The puzzles are excellent, and some of them really make you think outside the box. I don't know if I've ever had to think laterally in a video game before, and I really appreciate that.
I find it insulting how easy and simple mainstream games are. No thought or effort needed on my part. Everything is a cakewalk. I'd like to believe even the lowest common denominator is smarter than that, but according to EA, Activision, et al, gamers are brainless idiots who can't handle a puzzle or a challenge.
I do wish there were more classes and races. That's the biggest detractor. I see no reason to replay the game. that said, great overall.
