Past the doors and down a narrow tunnel
Edging past the half shut doors you find yourself in the caves. The lift is behind you. These caves run through the whole of H2G2 town and their many tunnels offer a maze of sorts. Fancy your luck? There is a prize of a doughnut for the person who gets out to the finish.
You can go left or right or straight on. The tunnels all look identically dank and are lit by an eldritch glow (why? Just because) that sketches the shadows and populates them with monsters. Are you brave enough?
