Bouncing ball in a box but the fps gets lower

Script

Sure, here's an example of a bouncing ball game implemented as a single HTML file using JavaScript:

In this game, a red ball bounces inside a box represented by the `game-container` div element. The ball's position is updated in a game loop using the `setInterval` method. The ball's direction changes when it reaches the boundary of the container. Additionally, the frames per second (FPS) gradually decrease over time, resulting in a slower game. Feel free to save this code into a file with the `.html` extension and run it on your smartphone's browser to play the game.
