Sure! Here's an example of a simple 3D rendered platformer game using JavaScript, HTML, and CSS. This game allows you to control a ball with shadows and toon shading effects. Please note that this is just a basic implementation and can be further enhanced with more gameplay features, levels, and graphics.
To play the game, you can copy the above code into a single HTML file, save it with a `.html` extension, and open it in a compatible web browser on your smartphone. The game uses the smartphone's orientation values (`e.gamma` and `e.beta`) to control the ball movement. Tilt your smartphone to move the ball in different directions on the 3D platform. The ball is rendered with shadows and toon shading effects using canvas API calls.
