Sure! Here's a simple Mario Kart test demo implemented as a single HTML file using JavaScript:
This is a simple Mario Kart test demo designed for smartphone operation. It includes a car element represented by a pictogram image (assumed to be `emozi_all/mario.png`). You can touch and drag on the screen to move the car around. The car's position is updated based on the touch movements. The game is enclosed in `
` tags and can be played as a finished game.
Please note that for this demo to work, you'll need to provide the `emozi_all/car.png` image file (replace `emozi_all/car.png` in the `background-image` property with the actual image file name or path).
