I feel this short film deep in my core. Being a person tormented by anxiety bouts when things spiral out of my control, I can understand the world described here very well. And how artistic and unique, the world being portrayed here, is. Give it a moment, for the technique to work its way into your head, and you will be swept right into it.
Also, hands down excellent craftsmanship. With only coloured pencils and paper, animation at its most basic form.
