The hall is in my kid's house, she got a witch once and broke the glass to kill it. I have a 25 tile radius circle floor in a tower that spawned a bunch of stuff before I put slime on it (bouncing house level) and the roof of the kids house is about 15 tiles square and she gets creepers sometimes. We can kill everything if we break the glass in her hall except baby zombies, where the glowstone has to be broken too. It seems zombies are harder to hit with a sword without breaking the stone, almost like it shields them.
