It is the sequel to the original Ore no Shikabane wo Koete Yuke. Unlike the original 1999 PlayStation game, the sequel will have characters fully rendered in 3D. The labyrinth levels are also rendered in 3D, with a fixed camera. The game system will be similar to the style of the original game, with basic enemy encounters, and decreased character strength upon running. The game will utilise the PlayStation Vita's camera using a face recognition mechanism.
