Grimm's Folly

Grimm’s Folly is a first-person adventure puzzle game about exploring a fragmented universe and uncovering the story of the scientist who worked in its dormant nuclear facility. After you fall into this world, you explore abandoned structures and caves, restore power systems, find hidden paths and solve puzzles. Reactivating the facility and opening a portal may be your only way home.

Explore the world

The interconnected world is open to explore, with puzzles woven into its environments rather than set apart in challenge rooms. Environmental and logic-based puzzles across the caves and research facility reveal what happened to Dr. Grimm. Your raven companion subtly points toward new discoveries and moves between areas as you progress, hinting where to go without explicit instructions.

Take flight as the raven

You can switch perspectives to control your raven companion, soar above the world and scout hidden or unreachable areas. The raven can also collect special nest items and take part in optional flight time trials.
