LD Entry: https://ldjam.com/events/ludum-dare/46/manual-breathing

Humans take automatic breathing for granted. Sentient marshmallow creatures must manually breath. In this game you take control of Biffy, a marshmallow creature, out for their morning jog - who is a real mouth-breathe.
An infinite runner where you have to press right-arrow-key to inhale; left-arrow-key to exhale and up-arrow-key for jumps. Take more breaths when running uphill and large breaths for big jumps.
