The controls are mostly fine. What I would change is that when you use your thrusters you don't fly in the opposite direction of where you are pointing but rather towards it (like the Jet-Boosts in "Richie's Plank Experience" or "Jet Island" work). Like you have thrusters at your hands that pull you and not push.
Because it's hard aiming accurately behind you and much easier if you can point at where you want to fly.
Also some Headsets with inside-out tracking don't work too well with controllers behind you, because they can't really "see" them.
Apart from that, explain the controls within the game and then they're perfect.
