It becomes impossible after only half a minute.
Im just going to be down to earth basic with you, the game its self was to easy, the sounds were ok, animation could be improved, death animation or movie perhaps? Maybe a story line and also medals(don't make them to easy to get!) and possibly better enemies like farmers shooting pellets or "shotguns" just to make everything more interesting. Other than that its a ok game.
the game wasn't done yet i hadn't written the code to make the cow grow yet. i am working on an ending animation but this is my first time using flash so right now this is what i can do
