All The Good Girls Go To Hell

You observe the planks one by one. Some are well worn, some are charred. You do your best to pick the most solid looking ones, but some are not too obvious. You choose one, but it cracks and splinters under your weight, sending your body tumbling into the weakened structure. The guide is fast behind you, scruffing you and shoving you down the bridge one step at a time. At the end, he releases you and ushers you quickly into the cave with an eyeroll.

In the struggle, you scrape your right abdomen. It bleeds a little, but will heal just fine.

Inside the cave, warm lava lights the way. Small pools bubble and small streams flow from tiny cracks in the walls. Several boulders act as stepping stones across larger gaps, and small wooden bridges span other areas. Around the walls of the room, a thin edge navigates above any threat of lava. It is clear you need to get to the end of this room if you wish to continue your journey.

What do you do?
