I just got Endless Ocean Blue World and ran into the same problem. The icon for Return to Boat was grayed out on the second map I dived at. I finally figured out that I needed to talk to my fellow diver. I mean not just clicking on her with the glowing pointed, but then do one more step. Click on the "Talk" button that came up. She will provide you instruction on how to leave the area you are in by heading South East of the boat.Hello everyone
I hope someone can help me .How do I return to the boat?When i hit down on the + button i get the tools/options but no return to boat.Am I doing something wrong or is the game messed up?
At least this moved me that much further in the game.
I must say that the initial tutorial was helpful, but I could not figure out that I needed to talk with the other diver.
