Forget Facebook’s Farmville (and stop asking me to find a home for your lonely black sheep), the new online game Kersplat! is a fun alternative, and it also reminds us of the challenges that people in Africa face.

The hosting organization Send a Cow developed the game to educate people about the virtues of “Magic Muck,” the high-nutrient compost that they provide to African farmers. The game includes a button that allows visitors to send a donation. You can also click on another button to learn more about the other projects that Send a Cow sponsors. (And you can keep playing until you knock me off the leaderboard.)
