Tale of the Fragmented Star

A lone girl stands abandoned on a broken star.
With the star deprived of its power, she can neither use it to escape nor inform others of her plight.
However, there exists a point on this star that intersects with another world.
The player, by standing on this convergence point and wearing the Otherworld-Viewing Device (VR unit), can enter the parallel world and communicate with the girl.
Together, they cooperate to solve the puzzle of restoring the star's power so she may be able to leave.
