Farmer Joe

Farmer Joe will follow your mouse wherever it goes. If you get close to one of the cows, it moves away from Farmer Joe. So you can steer your cows into the gate at the bottom right. However if you end up touching the cow, the cow gets scared and dies.

Try to get the best score, by doing it fast, not killing anybody, and gathering all your cows.

TLDR: Steer the cows with your mouse, but don't touch them.
