In this Puzzle/Adventure game you must guide Niko through a mysterious world, utilizing items, characters, and the environment to progress. The life of a lost child and the fate of a steadily decaying world hang in balance, and not everyone—or everything—is interested in preserving them either.

You are to guide a child through a mysterious world on a mission to restore its long-dead sun.
...Of course, things are never that simple.
The world knows you exist.
The consequences are real.
Saving the world may be impossible.
You only have one shot.
