SmartCart: bridge app analytics for September 9

This is a physics puzzle game. Players use their fingers or mouse to draw lines on the screen to build a rainbow, helping the little princess in the basket eat lollipops. The game tests players' engineering thinking and creativity, requiring reasonable planning of the shape and structure of the rainbow to ensure that the little princess can pass smoothly. If the rainbow bridge is not designed properly, it may cause the basket to fall or collide with obstacles, resulting in failure. The game contains multiple levels with increasing difficulty, simple controls, realistic physics engines, and challenging level designs, providing a relaxed and fun gaming experience.
