It's not bad, per se, it's just ... nothing spectacular. The puzzles didn't seem to be particularly challenging or inventive. The descriptions, writing, and characters seem to be completely bare-boned, with nothing that really makes me care about them. If the characters had been more three-dimensional, I think I would have liked it a lot more. The "mystery" part of the game disappears after your first fail (and you'll probably fail the first scene many times), and that took a lot of the experience away from me.
As is, it's not a bad game to wile away some downtime if you feel like relaxing and not reading too much, but don't expect to come out with a fresh perspective or anything substantial like that.
