You turn on your flashlight and shine it around you. You're surrounded by water, and the 'floor' is actually a floating island made of moss and grassy plants growing together to form a mat over some foul smelling muck beneath. You notice a small boat shored upon one side of the island.

You make your way to the boat slowly and carefully. It contains two oars as well as a couple of torches and an antique-looking metal lighter. You open the lighter and hit the flint to find it works. You grab a torch and light it. Flames erupt from the end of it, showering the area in light. You notice a metal bracket towards the back of the boat and find the torch slides right into it. The light reveals the forms of snakes and rats scurrying between the tall plants.

You push the boat into the water and hop in. A current begins to carry you away as soon as you're in the water. The enormous chamber you're in begins to narrow until you can see you're in a natural cavern. Ahead it breaks into two passages that look relatively identical.

Do you steer the boat left or right?
