Nice puzzle game, and great interpretation of the theme: science fiction meets Old MacDonald. The intro text was tops. It was a little difficult to figure out what the bad guys did. I liked the strategy play-style, and the feeling of herding cows with a UFO. Having the spaceship far off the ground made it a little tricky to line up with the cows and dash on over. Even though the art style was simple, it fit the game. The cow-face abduct animation was nice. I liked that you gave a few different sound effects for the same action, especially since this is a game where you spam the controls to get across the map quickly (at least, I did). Having some music might be nice, but silence is okay for a thinking game. Better than an annoying track.
For some reason, on certain levels, I would either run out of milk or win with a lot of milk left over. I tried to use tornadoes to save on fuel (i.e., M.I.L.K.). The bullets seemed relatively easy to dodge (same goes for cows, unfortunately). I found myself trying to line up with a cow from a distance of at least two blocks away to prepare my dashing direction. I found it helpful to hone in on him from a distance, like a rook's line of control, and if he steps into my path, I can dash. Otherwise, he's in a smaller box. The hardest part was trying to get to an opposite end of a map after abducting a cow.
