About This Demo

Illuminate—or perish.
Every step in Illumination of Mansion is dangerous. You wield nothing but a lantern and pure skill to map an haunted mansion tile by tile. The floor plan is a living puzzle; one wrong move awakens the heyulas beneath.

2.5D-Immersive Minesweeper Puzzles!

Navigate hallways and chambers as you tackle classic Minesweeper logic mapped onto a mansion. Simply throw your cards to reveal tiles, count adjacent heyulas, and clear every shadowed corner. No gadgets, no upgrades—just pure puzzle mastery.

Dark Fantasy Horror Art!

Step into a richly detailed hand-painted fantasy. Encounter stylized werewolves and haunting heyulas against a backdrop of flickering torches. It’s atmospheric mystery, not jump scares.

Grid-Based Strategy!

Every chamber is a carefully designed grid where one mis-step can send you back to the entrance. Study your patterns, spot safe zones, and push your deductive skills to the limit to illuminate deeper reaches of the mansion.

Mysterious Creatures & Clever Traps!

Face a enigmatic foes—werewolves prowling the corridors, wardens standing sentinel, and heyulas hidden beneath tiles. Be careful to vents, projectiles, and cracks. Key-finding and Sokoban-style block puzzles add layers of intrigue as you reveal the mansion’s secrets.

If you find it easy, wait for it coming more soon.
