Launch your hedgehog (pull it to the bottom part of the screen) hope you get about $1000 on your first launch, buy the level 2 radar and the level 1 fuel sucker, spend the remaining money on fuel tank, on 2nd day it will be much easier to get money, just hit as many platforms as you can and you should be able to get about $9000, buy the last level of fuel sucker and radar, spend the remaining money on the fuel tank then the rockets, then the launcher, on the 3rd day as long as you don't run out of platforms it should be easy, you should never run out of fuel, if you can't see any platform just go full thrust left and you should hit one pretty soon getting you back on track, if you have to choose platforms colors always choose: purple, then yellow, then green, last blue. Got the hard badge on about 15th try.
