You are the last descendants of The Professor, an eccentric inventor that people knew very little about. He passed away recently and you’ve inherited his estate, including the large, gloomy mansion. As you explore your new mansion, you come across what appears to be a laboratory! It seems he was building something quite interesting and you find a note begging you to continue his work. The Professor has trapped you in the mansion until you do!
