Sure! Here's an example of a simple game based on Among Us and Sonic using JavaScript and HTML. Note that this is a basic implementation without graphics or complex gameplay, but it should give you a starting point to work with.
In this game, you control a player represented by a rectangle on a canvas. You can move the player using the arrow keys on your smartphone. The game window is represented as a 400x400 pixel canvas.
When you load the HTML file on your smartphone, you will see the canvas, and you can start moving the player around by tapping the arrow keys displayed on the phone's screen.
This is a basic starting point, and you can add more features, graphics, and gameplay elements to make it a more complete game.
