144 :) just become a huge ball that has spikes and stay in the middle, any balls that come down will fall off or will pop against your spikes, just need to be lucky to get the right powerups and avoid a 2nd spike powerup
after first level, buy a thruster for 2nd level, you dont need it to beat the level but you get more money for the further u go, use it as soon as you fire, on lvl 3 buy 3 thrusters and any extra money on skis, use the thrusters all together after you fire. The clouds should have disapeared so when you come back down watch the clouds & forest for when you go to use your skis. From there on out its quite easy.
