A free program for Android, by Gregory C Miller.
You are a time warrior, a hero who must fight to save the world. To do so, you must travel to the world of the past and present, and unite the different tribes in order to find the key to defeating the demon who is threatening to devour the light of the world.
The different tribes have unique units, and you can combine the powers of the units to create a more powerful warrior. The more powerful your warrior is, the more you can conquer and the more you can earn.
The different units are also useful for defending your territory. You can construct buildings to increase your power and to protect yourself from the demons. The different buildings are also useful for finding the best strategy for defeating the enemies.
You must also learn how to use your magical powers to your advantage.
