We tried it and from the last friday we are on official Unity website. Even as a featured game. Cool! :)

DARK TRAIN is story-driven adventure with dark oppressive atmosphere. We believe that adventure games may not be only a "point and click" experience and therefore we decided to create a strong narrative game with direct action gameplay. The visual art processing is based on our own handmade papercut formula. In-game sounds & OST are also partially made with paper instruments and by mixing of samples. Detailed information from the development process can be found here on our blog or social media profiles. DT is expected to be finished in 2016, starting with Windows, Mac, and Linux.
