Lobby Loitering

As he's exploring around in a dying mall, Marcel catches word of an abandoned store somewhere on the property. Interested in that more than any open shop could, he goes looking for it. Lo and behold, he finds it, and passes through a portal to another reality without even realizing it. After meeting a mysterious entity in a hotel room, Marcel must find and explore a multitude of different alternate worlds by passing through a series of mysterious portals to hopefully get back to his home dimension.
In this game, you explore an array of hotels in an attempt to find the portals within to travel to the next world over. Each hotel is self contained, and is a story in and of itself. Talk to the people around you, help them with their daily struggles, complete tasks, and solve mysteries, all while being unable to directly communicate with them due to Marcel's mutism. There is no combat and no game overs, only logic puzzles and laid-back forwards motion.
