Thanks for playing. :) You can move to any tile without any immediate consequences. The consequences are later on down the line - if you take the wrong path, when you reach a lighthouse the dialogue changes (basically you've lost the game).
Oops! Looks like you found a bug as well when moving between the different rooms. Thanks for letting me know. I'll have to sort that out.
Thanks for the thumbs up for the rest of it. :)
