I don't think this is a bug, but in the underwater tunnel at the beginning of episode three, I can't seem to find my way out. I get to the end of the tunnel and can't leave and run out of time. I was just wondering what I am supposed to do at this point. Thanks
Actually, I had the same problem with the first underwater tunnel; the circles were not visible. What you have to do is go up (or down) until you are ~5-6 squares from the top, then press the action button. That should allow you to exit the underwater tunnel.
