Not sure what you mean by “the passage east,” but I don’t recall putting any one-way passages in the game so it sounds like a bug. If you could clarify which passage you are referring to, I’ll take a look and try to get a new version out.
Thanks! I mean the passage using the east orb, when I go that way and try to go back it won't take me back to the little grove with the three passages opened by the north/south/east orbs. So I'm stuck in the eastern area because I can't afford a galleon yet and I can't go back.
