Project Shadow is a Relationship Game, based on two games: Persona 3 & 4. The idea behind is that you are to save 5 people from becoming shadows.
Shadows are beings that possess people to corrupt them or others using past sins or inner demons (alcoholism, addictions, etc.).

And there is a known issue. It says something about strict mode...Don't worry and just head in. The game works fine.
Thank you and have a nice day.
