Thanks for the feedback. Since we were restricted from using text, I couldn't outright tell the player to defend the crops. I figured most people would just immediately lose some crops, maybe all of them before they figured out they needed to scare away the birds. Maybe there was a way to convey that message without forcing the player to fail, but I decided that allowing the player to discover the rules rather than spell them out would work well enough (it was also less work ^_^).
