Sure! Here's a simple shooting game implemented as a single HTML file using JavaScript. It uses pictograms for the game elements. Please note that this is a basic implementation and can be expanded upon as desired.
In this game, the player is represented by a pictogram image and can be controlled by touching and moving on the game container. The objective is to avoid collision with the falling enemy pictograms. If the player collides with an enemy, the game over message will be displayed, and the page will be reloaded to restart the game.
Note: Remember to replace the placeholder URLs (`emozi_all/player.png` and `emozi_all/enemy.png`) with the actual image URLs you want to use for the player and enemy pictograms.
