Sure! Here's an example of a simplified PSX-type game implemented in a single HTML file, using JavaScript and enclosed in script tags:
In this example, the game displays a canvas with a pictogram image representing the player character. The player character moves diagonally across the canvas from the bottom right corner to the top left corner. You can replace `emozi_all/game.png` with an actual pictogram image of your choice.
Please note that this is just a basic example to demonstrate the structure and functionality of a PSX-type game. You can expand and customize it further based on your requirements and desired game mechanics.
