[CS3113]Exercise 2: Marble Maze

**Note Before Playing the Game:

• Use Up, Down, Left, Right keys (Or W/S/A/D keys) to move the balls.

• Press the space to invert/revert gravity of the ball(player). When there seems to be no path, try to invert/revert the gravity.

• You have to touch (collide with) the finish line to trigger the next level. There are three levels in total for the game.

The goal of the game is to make the ball to the finish line by passing all the tracks with invert/revert gravity. The first level is very easy, which aims to tell the player how to operate the game. The tracks have rails to prevent the player from dropping out from the track. The second level involves moving parts (cubes), tilted tracks, narrowed tracks, and changing direction of the tracks. Some tracks doesn't rails. The third levels includes more moving cubes and one moving track to transfer the player to the other end.
