Many people have been commenting about not being able to land well which is on us for not making it more clear. There’s a strict cutoff for ‘perfect’ landings after which you’ll preserve all your speed. But all ‘ok’ landings aren’t made the same (can be anywhere from 50% to 99.99999% preserved speed). In fact likely most of your ‘ok’ landings preserve 90%+ of your speed. Regardles, thanks for playing the game and we’re glad you liked the theme!
