Auralux

Auralux is a minimalist real-time strategy game in which you only manage one type of unit. Your objective is to conquer, bit by bit, all the nearbye nebulae.

To do this, you must wait for your initial nebula to generate sufficient units (colored dots). Once you have a few, you should send them to conquer new nebulae, which might be 'free' or conqured by an enemy color.

To snatch a nebula you just have to send enough units to destroy the enemies and the resistance of the nebula itself.

Auralux is a beautiful game, with very simple but beautiful graphocs; a very relaxing soundtrack, and extremely simple and fun gameplay.
