Luminati is a first person puzzle game that uses gravity to explore a 3D environment in a far off galaxy. The game makes full use of 3D geometry, as you travel upside down, right side up, sideways, and a variety of other directions to make it to your goal. The shifts in perspectives were heavily inspired by MC Escher, and they truly bring a new approach to exploring 3D environments.
This game takes place in the far future where the heat-death of the Universe is drawing near. You play as a drone in a mysterious abandoned space station whose job is to activate the facility in order to revive the nearby star. The station has various gravity altering systems in place as a security measure to deter intruders. It is your job to reactivate the system's start to make the star system habitable once again.
