Reposting @Noraslow becauses it's a great suggestion and may get lost: "It would be nice, after having technically beaten the game before getting the hard badge, that one could fast forward or restart completely botched attempts at it (where you know for certain that flight didn't collect 100 space stars). With all the upgrades at too low an altitude it can take some time to finish a botched flight toward that goal."
Okay Kongregate won't allow deleting or editing of comments for some reason, but i found a solution for all of you who, like me, couldn't get past level 2:
DISABLE your virus checker. The moment I did that, suddenly the game actually started to make sense. Don't know how this game got past beta without someone testing it against an active checker, but that's the problem. (No other games I play on Kongregate have this problem)
Give it a try and you'll see.
