Owlboy is a platform/action-adventure video game created by Norwegian developer D-Pad Studio.

Explore a vibrantly crafted pixel world in this flying adventure platformer.

Being a mute, Otus struggles living up to the expectations of owl-hood. Things spiral from bad to worse with the sudden appearance of sky pirates.

What follows is a journey through monster infested ruins, with unexpected encounters, and burdens no one should have to bear.

From Wikipedia: "Owlboy is set in the land of the sky; the islands of the world below have been separated by a catastrophic event. The player controls a boy named Odus, who is a member of an owl–human hybrid race called the Owls. When Otus' village is attacked by a band of pirates, he sets out on a journey to save it from them."
