How to beat 6000 feet : First, buy and max all. Then fly with a air resistance of 3%(so that you gain altitude, up, not down). Use your rocket till' u are at 200 in "speed". When u sink to 175, use your rockets and get back up to 200, repeat till' you run out of fuel, then let it glide.. (this is not my idea it is lukeaye's)
