So on one hand, hey, fewer falling monsters. On the other hand, the bats can still fly in the sides from the chasm. And they squeak constantly, except when they set themselves on fire in the lava fall, when they scream instead.
But on the other hand, this is one of the most comfortable chambers I’ve dug, probably because there’s lava warming it, but not making it too hot to tolerate. If it weren’t like a hundred meters underground I’d move my stuff to this location and make this my home.
