Krome

You control one dot, which will move around the circle. Hold space to move away from the center and release space to move towards the center. As you move you will leave a trail of same dots.
Your aim is to avoid the dots and do as many laps as you can. Try to collect white circles, due to they will cause an explosion which will destroy some dots. Every three laps the color will change.
You can only collide with dots of the same color, but old dots will remain until that color is active again unless destroyed by explosions.
Have fun!
