Restart level should be 'r' not (or, as well as) 'backspace'. Almost every puzzle game has 'r' as 'restart level'? I'm right handed, and this is a game heavily using a mouse, why do i need to keep reaching over to the right hand side of the keyboard with my left hand?
Bored with the amount of times i haven't made it to 20,000ft because of something directly over the launch pad, and very little time to dodge because of the zoomed in camera. Why is the rocket central on the screen?!
