A Hollow Doorway is a meditation on the meaningless. A love letter to existence and an introspective look at the heart of purposeless infinity. Desperately swipe and spin your doorway in a futile attempt to match the rotation of rapidly approaching concentric walls as sweat pours from your armpits and your soul pours into your trembling thumb. It's fun!
