I want to believe

Bob is a typical happy farmer. One day when Bob was bringing his cows back to the butcher house, suddenly some creepy alien spaceships started to attack his animals. With the arrow buttons (or A, D), Bob is going to move as you wish and you can help him to save his cows by throwing magical bottles and exterminating the aliens (click). Make sure that the cows are following him and that they are not frozen by the aliens (red cows). He wants to believe that all his cows will arrive at the butcher house safely. Help him to fulfill his dream!
