Gravity Den casts players as Den, a one-eyed alien stranded after a spaceship crash. The goal is to help him reach his lost ship, with gravity manipulation shaping the journey rather than serving as a simple obstacle-clearing trick. This gives the game a clear adventure premise: navigate an unfamiliar planet by changing the forces that govern movement.
Den can travel through walls and across ceilings, while redirecting gravity can send him flying through the air. The game describes three large locations, each containing 50 levels and a different assortment of traps and obstacles. Stars collected in levels open rooms with more complex challenges, adding optional goals alongside reaching the exit. Players can also try to finish levels faster to improve their rankings, making route choice and execution part of the design.
The listing identifies Gravity Den as single-player and includes Steam Leaderboards and Achievements among its features. Its central appeal rests on experimenting with gravity, negotiating varied hazards, and refining runs through collectible and time-based objectives.
