It would be more of a challenge if standing sufficiently far from the final boss wouldn't make him totally unaware of you.
Great game, tho 5/5
i'm sorry... i fly solo!
It's really a good game, or a wannabe good game. Some hints: 1) way not challenging: the levels are poor designed and not stimulating, too repetetive. 2) the no-fly-zone pet is uber. 3) I finish 30 levels with 3 stars and not a single script that says: HEY THANKS MAN, YOU'VE DONE IT!!!???!
