fault - milestone one is a Science Fantasy Cinematic Novel game created by ALICE IN DISSONANCE. This game follows the story of a princess named Selphine and her Royal Guardian Ritona. Their homeland of Rughzenhaide is devastated by a sudden assault, and they are forced to escape. However, they end up teleported into an unknown forest full of vegetation they don't recognize. The atmosphere is thick and heavy, and there is no sign of life, which is very unusual for such a lush forest. Something is wrong about the land, but they are too startled to notice what. The game features a unique 3D camera system for a visually immersive reading experience.

The game has a Director's Cut version available on Steam, which has additional content and features from the original Japanese release, all thanks to their Kickstarter backers. The game is categorized under Adventure and is a series of Science Fantasy Cinematic Novels. The episodes are called "milestones" and are scheduled to be released periodically. You can switch between Japanese and English by pressing the J and E keys, respectively. Follow Selphine and Ritona on their journey of a lifetime back to their homeland of Rughzenhaide and uncover the mystery of the unknown forest.
