Yes, one of the game's leading charms is its story. To sum things up shortly, the player becomes a magical beam of light and must direct a girl who's transformed into a magical orb through a series of puzzles. It's strange, we know, but we wouldn't have it any other way. The nonsensical premise is what spurs a mellow, easy-to-understand puzzle adventure game, that's oozing with style.
The interplay between the light and the orb is well constructed. The orb is attracted to the light, and cannot move without it. At first, the light is used simply to get the orb from point A to point B. However, the game becomes more complex. The orb can transform into a variety of elements: wood, glass and metal. In its metal form, it can jump when a strong beam of light is placed on it. Wood can float across water, and glass can traverse its depths. However, players must be careful: overexposure to strong light will burn wood, and shatter glass.
