Does the button "re-center handheld" bring you near the tutorial? I'm curious also HOW far away you are, since I thought I had code that should prevent people from being where they might end up via errors of some kind... but yeah. Let me know. Also possibly if you can, search the logs at Appdata/LocalLow/BarShiftGames/PortableEmulator/Player<-prev>.log and see if in those files contain the words "Exception" "error" or "crash", to bring up any sections of code that look like error logs?
For instance this is an example error:
NullReferenceException
