Broken Age 

Broken Age is a 2D point-and-click adventure telling you the stories of a young boy and girl leading parallel lives. The girl has been chosen by her village to be sacrificed to a terrible monster, but she decides to fight back. Meanwhile, a boy on a spaceship is living a solitary life under the care of a motherly computer, but he wants to break free to lead adventures and do good in the world.

The game has good graphics and music tracks. The original soundtrack was composed by Peter McConnell and recorded by the Melbourne Symphony Orchestra. This is available for PC, MAC, and Linux desktop platforms.
