1.0 HD (Humble Indie Bundle #4) released on 13 December 2011
NightSky is an action-puzzle game that offers an ambient gameplay experience unlike any other — cerebral challenges fill uniquely designed picturesque worlds. Each of these worlds is broken into different areas in which the player must maneuver a sphere by using realistic physics to advance. There are no enemies, no bosses, and no violence in NightSky.
