Full screen. Most likely to watch without full screen but both are good. Stare at the beautiful invisible sprite going around and each line following. Wait till the screen is full! Then, observe the strokes still making. See the past strokes? This will relax you. Make sure you watch this. OR NOT RELAXED!! CAUTION--@Leavya GOT EFFECTED! BY AN EYE DISEASE BECAUSE OF THIS SO DON'T STRAIN YOUR EYES!!
