Making it tap-only would definitely be the main thing. I'd try it with just that before changing anything else. The other complaints were just quirks, while the overturning felt like an actual control problem and the guy I saw stream it seemed to have the same issue.
Giving the player more gas could be a difficulty modifier? Like the current amount could be Hard, with Normal being more lenient and Easy regenerating over time. Another modifier could be the strength of gravity.
