Sinners is a Japanese-style visual novel. Instead of an open world game, this game will be more linear where choices will affect the endings.
You will play the role of a freelance programmer. One day, you receive a mysterious letter. Depending on your choice, your life is intertwined with up to five other girls. In the end, maybe you can find out who sent you the letter? You can completely skip any storyline if you don't like it.
