Scarecrow Defender
This is a really cool Mission Command style game where you have to defend your scarecrows from the incoming raven invasion. Shoot seeds at your scarecrows to make them swing at the ravens. Repeat until the invasion is defeated or your scarecrows are picked apart. It's easy to learn, difficult to master, but I'm sure that you have nothing better to do, so get your scarecrow on.
A Murder of Scarecrows. My best score is 293, but I'm sure I can do better.
