i don't know if this is a glitch or anything. when u enter a place or whatever. make ur plane go backwards. then it will freeze wait for it to unfreeze and your plain will get stuck but still move. don't press the rainbow star thing because it will stuff you up. just press your fire bar untill it runs out. you can do this for as long as you want. compleeting the whole game in like level day 5. i hope this helps :)
