Chicken Attack!

Chickens are trying to cross the road. We don't know why, but it can't be good. This is a tower defense game made in less then 24 hours for HOGJam #2. The theme was "Free Chicken, Weird Chicken."

Notes

Controls: Purchase farmers and cannons using the buttons, and then place them in the road. Click on them to upgrade, repair, or sell. The F key toggles full-window mode. (Use with F11 for full-screen.)
