Ha ha, moo. You can't go wrong with a game that has flying cows. I also really liked the windowed presentation.
P.S. not sure what the intended strategy is. At first I tried dodging the clouds, but the saucer is a bit finicky for that. So I decided to just stay in one straight line at the top of the screen and quickly pick up the cow when I hit a cloud. Got to 851 like that. ¯\_(ツ)_/¯
