Die in Seven Days

Death in Seven Days (Japanese: 七日死 / ナナシノゲエム) is a survival horror adventure game for Nintendo DS where players must complete an in-game curse within seven days or face death. Gameplay alternates between a first-person 3D exploration mode using the DS vertical orientation, touch screen for item interaction, and D-pad for movement at a slow pace to heighten tension, and a side-scrolling RPG mode on the horizontal DS screen featuring classic turn-based battles with bizarre glitches and character name swaps that warp reality. Story follows university student protagonist investigating a mysterious viral game delivered via TS (Twin Screen) device; real-world events bleed into the in-game horrors involving university seniors, lovers, and a cursed hospital, with characters like Odaka (the obsessed senior), Riko (Odaka's girlfriend), and Nameless Game characters (e.g., protagonist's real-world self, hospital professor, and director Shioda). It stands out for its meta horror blending meta-fictional RPG mechanics with psychological dread, effective use of DS hardware for split-screen tension, and immersive atmospheric storytelling that blurs game and reality.
