I couldn't work out the game at all.
Is he supposed to be delivering pizzas for sex at some point - or just endlessly trying to shoot down as many skyturtles as he can as he careers his crazy way through the sky?
As you may have gathered, I am not one for shoot 'em down games, and so am doubtless missing something - possibly everything.
The positive rating I'm giving is only a) for the "losing" final splash screen - if getting gangbanged/monstered/consumed by the beauties is losing, why would he ever want to win, as others e.g. Malfluent have pointed out (maybe they are cannibals, but what a way to go) - and b) for the two beauties at the very start of the game, before it all kicks off. In other words, what I like is absolutely nothing to do with gameplay I don't understand.
Personally, I'd say make more sex pictures, and less basic Supermario/Donkeykong type throwbacks! But what would I know? :D
