Undertone Continuum is a free arcade game where you must kill enemies by firing a beam of matching color into them.
Shoot your beam through an enemy of any color to mix the two colors and thus being able to take out other color enemies. note that too much mixing always gives gray. When in doubt about color mixing, you can look at the paddle for guidance.
The goal is to defend the big flowerish thing in the middle. They`ll hurt you though. go close to the flower to heal. take note that you`re draining its health by doing so. The flower will, unlike you, regenerate though.
