Chapter 61 adds the *Town Portal* item, giving the adventurer a quick way to return to town. This is expanded into a more general teleportation system.
Chapter 60 uses layered procedural generation to generate two distinct map types, and blend a transition between them. It also adds nasty lizard monsters!
Chapter 56 introduces a new set of levels: the limestone caverns. Lighting is added, along with a new theme. The first cheat mode is also added to make level traversal during development easier.
