Sure! Here's a simple implementation of a Marble Race game using JavaScript and HTML:
Marble Race
In this game, you can control the movement of the marble on a race track using the orientation of your smartphone. The marble will move horizontally based on the device's gamma (tilting left and right) and vertically based on the device's beta (tilting up and down). The game starts automatically when the page loads and stops when the page is closed or refreshed.
Please note that this is a basic example and can be further enhanced with additional features such as obstacles, levels, and scoring depending on your specific requirements.
