this game is realy great
Duality: Final Order
A downloadable game for Windows
You are the master of the Yin-Yang blade. Through each attack, the blades adsorb life from the enemy and accumulates "Chi". While fighting, you need to keep balancing the opposite "Chi" to enter the "Nirvana" state and launch the big blow.
In this prototype, you can fight the enemy with clicking right or left mouse buttons (We left the accumulating "Chi" feature for the next iteration)
Feel free to check of the Web Comic it's based on:
