well, the problem with unity is that the save game has to korrespond with the entries in the registry. so you have to change the entries in the registry and the save game, too. i was trying a bit, but did not exactly figuerd out, in which way i have to change the registry.
maybe i will try...
first try: i was stuck. could not get back home for a sleep. maybe it was wrong, that i put in PJ and left the house.
second try: no foxes, no improvement. tried everthing, but its getting boring, always doing the same... any hints? is there a walkthrough?
