Sure! Here's a simple implementation of Pac-Man as a single HTML file using JavaScript:
In this implementation, the game board is represented by the `game-board` div element with a size of 500x500px. Pac-Man is represented by a div element with the class `pacman` and is placed at the top-left corner initially. You would need to replace `'emozi_all/game.png'` with the actual path to the Pac-Man image. Pictograms or images can be used to represent Pac-Man and other game elements.
You can control Pac-Man's movement using the arrow keys on your smartphone. The `movePacman` function updates the position of Pac-Man based on the direction provided and the `handleKeyPress` function handles the keydown events to trigger movement.
Please note that this is a basic implementation and does not include any game logic, obstacles, or ghosts. You can further enhance this implementation to create a fully functional Pac-Man game with scoring, levels, and other game elements.
