Chromaplex is a colorful action game with simple controls. Just try to remove the moving particles by catching them within a circle drawn by your mouse. Be careful to remove only particles which colors match the playfield background.

Catch and remove the colored particles by surrounding them with a circle. To draw a circle simply press and hold the left mousebutton, then move your mouse. Your circle will automatically be closed by releasing the button. Be sure to only surround particles which match the color of the playfield background. Removing wrong colors will drain your energy. The inner circle at the background displays your energy level, while the outer one shows the time remaining until the color of the background will change.
