I really liked the idea, and the realization is great! I felt that the hammers were a bit unfair as you have no way to speed up or down the chickens to avoid them. My favorite parts were the little steps that allowed me to group up my chickens :D
Yea, the unfairness is everywhere in this project (was going for more a rage inducing thing). Hah i'm glad you used those steps like that! I found myself doing the same thing. Thank you for the great feedback :)
