A Rolling Ball Demo

Level 1: The player can control a rolling ball that moves and jumps across the grassland. When the ball hits a cube, the color of the cube will change and a "Congratulations" user interface and a "Next Level" button will appear. After clicking the button, the player will enter a maze. 

Level 2: Try to find the cube in the maze while enjoying Bob Dylan's song "Like A Rolling Stone". Click the "Replay" button to replay the maze level, and the "Next Level" button will lead you to the third scene.

Level 3: Control the rolling ball to find the powerup, then defeat at least three enemies to hit the cube to get to next level.
