Go back to easier area to get「Crown - Space Dash」FULL(a color bomb at stage beginning), and earn some items,especially color bomb。Then go back to 2747,using color bomb item before start playing ,try to see if the two color bomebs together. I think it's the most important thing at 2747. Second,try to make another color bomb…
I finally passed. Go back to 「easier area」 and earn some items(hand&lollipop&color bomb are good),then get 「Space Dash」full。Back to 2744,use color bomb at the beginnig,see if two color bombs can be together。If NOT,2744 almost can't pass。I think it needs TWO times color-bomb together at 2744,and some items,and some lucky。
