Sure! Here's a simple shooting game implemented in a single HTML file, using JavaScript and pictograms:
This game is a basic shooting game where you control a player character at the bottom of the screen and shoot bullets to destroy an enemy character moving horizontally at the top. You can use arrow keys to move the player character left or right, and press the spacebar to shoot a bullet. If the bullet hits the enemy, you win. If the enemy hits the player, the game is over, and you can restart by closing the alert window.
Please make sure to replace `emozi_all/player.png` and `emozi_all/enemy.png` with relevant image files, and adjust the game container size and styles as desired.
