iQ-Marathon (a.k.a. Cow Maze) (It's all over the place, so this is just a Google result list; pick your favorite game site to play from.)
The directions are mostly in German (and with lots of net.speak at that), but as long as you know that "Q" means cow and "pokal" means trophy (and when there are multiple cows, only the grey cows need to reach the trophy), the rest of the directions and the game itself should be pretty self-explanatory.
(I've tried making an animated LJ icon of the dancing cow at the end of each level--'cause it makes me laugh every time, in a "Lion in Kenya" sort of way--but I just can't seem to get enough of the right screen shots to make it look right and move smoothly.)
