Sure! Here's an example of a simple jumping dog game implemented as a single HTML file using JavaScript and enclosed in script tags:
Score: 0
In this game, the objective is to control the jumping dog using the up arrow key or space key on your smartphone. The dog will jump when the control key is pressed, and the score will increase by 1 every second. The game is displayed within a 300x150 pixel container, and the dog is represented by a pictogram image.
Please make sure to replace the `emozi_all/dog.png` URL within the CSS code with the actual image URL of a jumping dog pictogram you would like to use.
