Sure, here's an example of a simple game implemented as a single HTML file using JavaScript and enclosed in script tags. This game allows you to control the movement of a camera through a random sequence of live cameras:
Camera Game
In this game, a red camera box is displayed within a game container. The game automatically starts and counts the elapsed time in seconds. After 10 seconds, the game ends, but you can adjust this duration as needed. Each time the camera is clicked or tapped, its position updates randomly within the game container.
Please note that this is a basic example, and you can modify and expand upon it to suit your specific requirements, including the use of pictograms or any other features you may want to add.
