I did this myself as well, it wasn't even purposeful! I sucked my first playthrough and lost so the S.S. Anne never sailed away. I returned with my... Lapras I believe, and searched around following a Mew theory. Tried turning the game off and using Strength on the truck for Mew, obviously didn't work, oh the memories :jess:
I have a hard time following directions and maps in games... as well as real life. :eep:
