The game looks good and implements the theme well. The gameplay could use some work, but that's probably because we didn't have enough time, as I've read in the description.
My first suggestion to make the game more fun quickly would be to put more milk buckets and make them affect all the lanes at all times. That way, it would have some level of strategy, like focusing on getting all the attack buffs first so the skelly guys can destroy the fances quicker, then speed last so you can push the cows faster.
Anyway, the idea is fun and I think the gameplay would work fine if you had more time to work on it.
