About
Imagine being a vector in the simulation.
Moving freely in 3D space with no constraints.
That is what you can do right now with your mouse (left: forward, right: backward) or your finger and if you have a gamepad, you can use it too - the best is to take your drone controller in simulation mode :D.
This mode is called the acro mode if you are not familiar with it,
you can learn more about it here.
