Lucid Fly is an artistic and very contemplative experience, It's all about free flying into a mysterious otherworldly city.
Take your time to look around everywhere, high in the sky or down in the galeries, some things are waiting to be discovered...
In the "Extras" section other mysterious places like the great pyramid of Giza, Stonehenge, or simply outer space are waiting for you.
Always look for the emeralds, they will allow you to navigate between levels.

Have a nice Lucid Fly !
