i am on the last guy. DR. robuttnick. the rad chaser level. you have to drive the time car in a parody of rad racer. the problem i am having is that when i get him to his last four bars of health, his rockets seem to get this heat seeking ability and i can't dodge them at all. so he hits me three times and kills me at this point. what can i be doing wrong? is there a trick or something i got to do that i am not seeing?
