In Chirality you can play in two modes. In both of them you should stay in the spotlight with your "orbs". You control your "orbs" in the same time, and in the first mode you have to avoid all the incoming reds with them. In the self-defense mode you can destroy the reds and defend the blue "orb" with the other one.
Your score can get miltiplied by getting the achievements in the game. Have fun!
