when you're having a run of bad luck, this is one of the most infuriating games i've played. it's really hard to convince yourself that the computer's NOT out to get you, but i guess you only really pay attention when it's unfair against you...
there's another way of getting over 1800 - the one i use is just doing the handstand trick for a split second over and over again, starting as soon as you take off, and carrying on the way down. you have to keep the balance going, and do a flip at the top as well. you can also do up to three extra short handstands once you've landed - as long as you bounce high enough. i got 2419 trick points! good luck.
