Nice idea! The first time I played windows firewall gave me a pop-up to allow the game, and when I returned to the game I didn't know where the UFO was. I spent 3 minutes trying to find it and when I did, it was bugged on one of the cows. So I restarted the game and followed the UFO around, had some fun saving the cows, even though it was generally easy (one time I had a bad angle between the trees and almost didn't save the cow!). Then I decided to shoot a cow early and the UFO got stuck again, so I guess there is a bug if we shoot the cows before they're getting sucked in. Nonetheless, I had some fun and the cows are cute. A scoring system would be great though
Nice job :)
