Sure! Here's an example of a simple game where you can control a character with a gun to shoot monsters. The game is designed to be played on a smartphone, and it uses pictograms for visuals.
To play the game, you can save the above code in a file with a `.html` extension and open it in a web browser on your smartphone. The game starts automatically, and you can control the character's movement by tilting your phone. Tap on the game screen to shoot at the monsters (represented by
👹) and earn points. If a monster collides with your character, it's game over, and your score will be displayed. To play again, simply refresh the page.
Please note that this is a basic example, and you can further enhance the game by adding levels, power-ups, or additional game mechanics.
