The Jet Pack Controls need to be fixed.
It's OK to have this as is now
"Shift" key for lift Off & for Landing. (Vertical flight)
"W" key to propel you forwards. (Horizontal Flight)
"S" key to put you back to Vertical flight.
As a professional Pilot (with thousands of hours flying)I would suggest that the actual directional movements, and the straight and level flying should be controlled by the MOUSE.
I should be able to hold a straight and level flight without having to keep pressing "Shift" to stay up.
Forward Motion is what keeps me flying witht the "W".
Also these control KEYS should be added to the CONTROL settings ... in the Settings nothing is mentioned of how to use the JETPACK.
I really hope someone reads this and pays attention to it.
