One thing I thought was kind of annoying when I finished my last/first play through of the game, was that for a couple of the monster zoos, the non-aggressive monsters with the ability to teleport would just flee the zoo. In a few of the levels I wasn't even able to find them so I didn't get the reward. Not the biggest problem, just kind of frustrating. Maybe if it was made so that monsters are unable to leave the zoo through means of teleportation magics that would help. Just a thought. But yeah, I just finished Dwarvish Moderation on Permadeth in one day, so I think I need to go outside or something now...
