I’ll second that. You really have to get a feel for stop/starting and tapping the jetpack constantly, like it’s a flaky old volkswagen 😉
Especially important when you’re running out of fuel – you don’t have to let Harry drop all the way to the floor when it cuts out – just restart it midair!
I can confirm I’ve learned to adapt, having played all the way through when I was 12 when my brain was more pliable :D. The controls are pretty well burned into my brain, and it plays no less fluently for me than any other platformer.
