Analyst notes (AI-assisted)

White Day: A Labyrinth Named School is a 2017 first-person survival-horror game set in a Korean high school, blending puzzle-solving, evasion, and romance mechanics.

This title has generated $1.34M lifetime on modest 208k sales, maintains 81% positive reviews, and still earns $3.87k/mo despite zero marketing touch in 30+ months. The high elasticity (1.35) and recent price drop suggest untapped demand at lower price points. Best fit for a publisher seeking to revive a dormant cult title with regional (Korean) cultural cachet and existing fan engagement through guided content strategy, localization expansion, or console porting. Most realistic play: revival.

• Risk: Player reports of save corruption and door-state persistence bugs; build stability may require engineering investment before re-launch.
• Risk: Extremely niche genre (survival-horror puzzle hybrid) with narrow platform footprint (Steam-only); console/mobile expansion risky without proven demand.
• Risk: Developer (SONNORI Corp) shows fading studio status with one title; ongoing support and patches unlikely without publisher intervention.
