Besides screenshots, the website also contains the following information in regards to what the game is about, and in regards to the game's main setting, Scala ad Caelum:

Spoiler: About

KINGDOM HEARTS DARK ROAD can be played easily with taps and swipes on your smart phone and is stress free with no complicated leveling or evolving! Level up through Auto Mode or enjoy strategic battles with bosses. Why did Master Xehanort, a major figure in the KINGDOM HEARTS series, become the seeker of darkness? That very mystery paints the story of his youth as he studies to become a Keyblade Wielder.

A world lined with grand structures cascading down peaks like stairs. Keyblade Wielders and the youth who aim to become such gather here, earning it the name “City of Keyblade Wielders.”

EDIT: It appears the site is inaccessible now, and seemingly went live by accident last night.
