FENER: Light Puzzle

One room. One light. Three questions.

FENER is a calm puzzle game built on the geometry of light. Walls cast shadows; you place the light, block it, or hide from it.

THREE CHAPTERS • LANTERN — place lanterns, leave no corner dark • CURTAIN — draw curtains, cut the protected ones off from the light • HIDDEN — predict the shadows while the lights are off, then flip the switch

WHY FENER? • Endless levels, each generated by algorithm with mathematically guaranteed solvability • Levels are identical for everyone: your level 23 is your friend's level 23 • A fair star leaderboard on Game Center • Fully offline; no ads, no accounts, no data collection • No timers, no penalties — just you, the light, and the shadow • Subtle haptics and a quiet soundtrack

A five-minute break or a long evening. Light is a gentle teacher.
