About Cyan Heart
Cyan Heart is a horror‑puzzle adventure told through a “selfie‑perspective” camera. You guide a girl who constantly films herself, solving puzzles and avoiding hazards while never seeing the forward path; only what the camera shows behind or below her is visible.
The world once relied on the Magenta Heart, an energy that could eternally mimic any phenomenon. After it turned cyan, the unstable “Cyan” corrupts objects and machines. The girl explores an abandoned facility alone, using her CSZ8x2 camera to uncover a hidden object that may halt Cyan’s spread.

Selfie‑Perspective Gameplay
The camera view is limited to what the CSZ8x2 records behind and below the girl, never the forward corridor. Players must rotate the lens upward or downward to locate clues, hazards, or puzzle elements that lie outside the immediate line of sight.
Because the camera is the sole visual source, checking behind and beneath the character becomes essential before each step. This design encourages careful spatial reasoning and frequent camera adjustments to anticipate dangers that would otherwise be hidden.
- Rotate the camera slowly to reveal hidden triggers before moving.
- Use the rear view after each action to confirm safe passage.

Cyan Energy Mechanics
The world’s original Magenta Heart could permanently mimic any physical phenomenon. After it transformed into cyan, the energy remains functional but unstable, turning any tangible object into cyan matter that can warp machines and living beings.
Cyan‑altered objects behave differently when observed through the camera. Players can decide whether to avoid these objects or exploit their altered properties to progress through puzzles, based on what the lens reveals.
- Observe cyan‑affected objects before interacting.
- Consider whether the altered property aids or hinders a puzzle.

CSZ8x2 Recording Device
The CSZ8x2 camera records video, enables voice communication, and logs data. Pointing it at objects lets the girl examine them or access machinery, while voice transmissions from companions provide hints.
All interactions are mediated through the lens, making the camera the central tool for exploration, puzzle solving, and narrative discovery. Its multifunctionality ties visual, auditory, and data‑logging aspects together.
- Listen to voice hints for subtle guidance.
- Scan machinery with the camera before attempting interaction.

Audio and Sound Options
Cyan Heart includes stereo and surround sound as well as custom volume controls. These settings let players adjust the overall audio mix to suit personal preference and to distinguish ambient sounds from voice transmissions.
Custom volume controls let players adjust audio levels to their preference. Players can raise or lower specific volumes to ensure that important voice hints remain audible alongside environmental sounds.
- Adjust volume sliders to balance ambient and voice audio.
- Test both stereo and surround modes to find a comfortable mix.
