IMPORTANT! You may think that the green turbo power-ups cannot be picked up at times. That is because picking up that turbo would go beyond your current turbo meter, this is a convenient way for you to not waste your available power-ups. Also never maximizing your turbo will encourage you to use it.
Move with the mouse, and avoid the purple blob.
Collect green shinies for turbo, hold Left Mouse to use it.
After 25 seconds, turbo replenishes automatically.
