This is a strategy game set in a mix between Greco-Roman mythology and an ethereal, deep atmosphere. As a divinity, conquer stars to build up your mana and unleash powerful spells on your enemy. You have two ways to win a battle: draw more constellations than your opponent, or simply annihilate him!
*EDIT* : thx for the comments!
For those who are stuck in level 9, it's not a bug: you must conquer every star to win the level. Remember: you can win any level quickier if you crush your opponent by conquering every star.
