The controls may be hard to some, but once you can handle it, it can be fun! ;D
Start/Stop engine: double-tap spacebar
Thrust: hold spacebar
Turn character: rotate camera
Tilt offset: W, A, S, D
Tip: Hold spacebar only when you feel like you need a force upward, don't use WASD until you've learned the basics.
Tip: Force is added to the direction of the top rotor, so tilt forward = go forward, tilt left = go left etc. So in order to slow down, you'd have to tilt yourself to the opposite direction you're going to; you're going forward, you have to tilt backwards.
Yes, I did make the helipack. No, I did not make the crossroads.
