There's some great presentation here!
I really like the off-kilter camera with its blurry focus and subtle vignette. I particularly love how the sprint speeds you up slowly until you eventually fall over. The farmer character is quite appealing in a cartoon-ugly kinda way. And the UI work is quite strong!
That said, I found the herding gameplay fairly dull. The comedy of the situation wears off while you're chasing the remaining chickens out of corners. I think you could really benefit from some kind of secondary herding ability, or making different size chickens easier/harder to herd, but as it stands, the main gameplay loop is kind of tedious.
Thanks for sharing this!
