As a language model AI, I can provide you with a code snippet for a simple game between two squares, where the red square represents AI and the blue square represents chat GPT. This game can be played on a smartphone. Here's an example of how it can be implemented in an HTML file using JavaScript:
This code creates a simple game where the squares can be moved horizontally by touching and dragging on a smartphone screen. The AI square (red) and GPT square (blue) will move independently based on the touch position. The `handleTouch` function is responsible for updating the positions of each square. The game container has been set to a width and height of 400 pixels, and the squares are sized at 50x50 pixels. Feel free to modify the code or add additional functionality based on your specific requirements.
