Our take on Hifuu Nightmare Diary ~ Violet Detector.

Instead of treating bullet patterns only as hazards to avoid, the game makes them photographic subjects. Capturing attacks can remove them, while framing the boss and the player affects the recorded score, replacing shooting-only progression with a camera-focused combat loop.

What is Hifuu Nightmare Diary ~ Violet Detector. ?

Play as Sumireko Usami, who visits Gensokyo only while dreaming.

Choose a day and a bullet-pattern dream to begin a short stage. Defeat the opponent while avoiding incoming attacks, then take at least one photograph to clear the scene. A photograph can erase the captured bullets and inflict greater damage on a boss when the boss is near the center of the frame. The photo gauge fills automatically and must reach 100% before a picture can be taken.

Holding Slow and Photo charges it faster, but prevents shooting during the charge. Recorded photos receive scores based on factors including the number of captured bullets, whether the boss appears, and whether Sumireko is visible. Story progression does not require clearing every dream scene.
