I really lived "Bird in a Wrought Iron Cage". It was effective, affective, and just the right length.
The other two stories didn't work as well for me. The first one started really good, and then felt like it degenerated into self-parody. In the beginning - trapped in a cabin surrounded by deadly spiders - it seemed like a really desparate situation, but one where there's just enough of a chance of survival to maintain suspense. But once the second ring, of deadly wasps, showed up, the game was essentially over. No more suspense. Hopelessness can be interesting; but instead of really examining it, more and more threats just kept being piled on. By the end, I wouldn't have been surprised if they would have suddenly noticed a bunch of polar bears would have showed up pushing wading pools full of sharks with lasers on their heads.
The second story was, for all its shortness, too long. The idea was good, but basically all it was a pompous jerk's self-congratulatory gloating. The fact that the guy was so full of himself ended up obscuring the horror of what he had done.
