Morrathil: Wrath of the Forest is a single-player action RPG for Android phones. It is drawn in pixel art, seen from above and played in landscape, with real-time combat.
The story
Morrathil was once the Keeper of his forest. Then the forest was felled and burned. Something grew around his grief and hid the Keeper underneath. That something is the Wrath of the Forest, and it is who he is now: an undead tree carrying blight, a rot that curses the living.
The Keeper is still in there. Each choice you make leans him toward one or the other.
Remnants of the forest survived, and they hold rings. Each ring is a shape Morrathil once wore. When he remembers one, a power comes back to him. He keeps that old shape even as he goes on changing.
