Marrow is a 2D, Cosmic-Horror themed, action-adventure game emphasizing challenge, puzzles, platforming, combat and navigation. Leap, crawl, slash and blast your way through the cavernous bowels of a menacing mountain in a quest to find your lost friends who now cry out for help, shrouded by the thick, living dark of the nameless peak's innards. A rotted town, crypt and Manor are merely the membrane which cover the deeper, undulating terrors left to decay countless years ago beneath the mud and rock.

Marrow's setting is a burial site, made with purpose to mask the devices and cosmic crimes of those who occupied the hill's once flat terrain, now broken and mangled within the mountain's insides.

Echoing within the hollows are the screeches and bellows of this realm's old inhabitants, shades and abominations seeking to forget the noxious truths and presences they uncovered with their unbridled experiments, attacking those who disrupt their shallow grave and mingling with the spirits of those seeking redemption, who are keen to guide you. You who might contain the grit and steely mind to face the mountain's darkest, imprisoned Secret and free them all from their sins.

Marrow will test your wits and reflexes, forcing you to face off against dozens of enemy types, either through avoidance or confrontation using the small number of still usable blades and relics left inside the mountain.

Search and explore every dark corner of Marrow's setting to increase your Grit (vitality) and Clarity (magic). Grasp new skills like Pyro-burst and Grit Regain. Use the last Luminous Orb to create tones, defend against enemy attacks and solve riddles. Enter the Fissures to uncover the Echo Realm, pull back the veil of reality and explore the world with a different perspective, but be mindful of the new dangers which dwell at the edge of normal perception. Light torches and braziers to illuminate your way, blast from spot to spot using the Orbital Anchors, and much more!

Look and Listen. The Orphans are lost within the mountain, but when nearby you can hear them chanting a familiar song, one shared between you and your friends. Follow the withering melody and send the lost children back to the mountains top, to the house on the hill.
