Lone Labyrinth is a turn-based JRPG where every choice carries weight, and every soul has a price.

A party of heroes sets out to defeat Morsophus, the malevolent Lich haunting the land of Isen. But the moment they enter his twisted tower, everything falls apart. Disagreements and distrust splinter the group; Each member believes they alone can finish the mission. Alan, a knight and the unofficial leader of the party, must reunite his party and save the day.

...But what if he didn't?

Alan harbors a secret: a pact with Miguel, a Devil who offers him a chance to revive his fallen mentor—at a cost. All Alan must do is claim three souls. Alan must choose to either be the honorable knight he was trained to be, or harvest the souls of those he once called allies for his own benefit.

Befriend or betray your former party members. Gain their trust and support in battle, or strike them down to unlock new abilities for Alan. Battle slimes, skeletons, and all manner of undead as you ascend Morsophus’s tower and confront the truth at its peak.

Your choices shape the world around you. With one dungeon and seven endings, Alan's personality and the ending of this tale morph with your choices.
