Grimm’s Folly is a first-person adventure puzzle game focused on exploration, discovery, and environmental storytelling. After falling into a fragmented universe, you begin exploring a world of abandoned structures, caves, and a dormant nuclear facility.

As you explore the interconnected world, you’ll restore power systems, uncover hidden paths, and solve intricate puzzles that reveal the story of the scientist who once worked there.

Piece together what happened, reactivate the facility, and open the portal that may be your only path home.

Explore and Solve at Your Own Pace

Grimm’s Folly emphasizes exploration and discovery. Most areas can be explored freely, with puzzles woven naturally into the environment rather than isolated challenge rooms. When you need direction, your raven companion subtly guides you toward new discoveries.

Take Flight as the Raven

Your raven companion is more than a guide. Switch perspectives to soar above the world, scout hidden areas, collect special nest items, and take on optional Raven flight time trials.

The raven also helps guide your exploration by moving between areas as you progress, hinting where your journey can continue without explicit instructions.
