I just played through it... it really picks up in chapter two. I like multiple playable characters and the Day of the Tentacle style mechanics to share inventory puzzles between them. It's a bit weird to have the usable items glowing (although I understand why since you said you wanted it to have a bit more casual adventure feel). I don't suppose there's a way to turn that off if you'd rather have more of a challenge?
I'm intrigued enough to want to play through the next chapters once they're out. It's not quite my humor style, but then again, neither was Hector: Badge of Carnage, and I enjoyed that.
