Sure, here's a simple shooting game implemented as a single HTML file using JavaScript. The game assumes smartphone operation and uses pictograms for visual representation. The player's objective is to shoot falling targets before they reach the bottom of the screen.
To play the game, you can copy the entire code into an HTML file and open it in a web browser. You control the game by tapping or clicking on the cannon emoji ('
🔫') at the bottom of the screen to shoot down falling targets ('
🎯'). The game ends when you run out of lives, and your score is displayed in an alert popup. Good luck and have fun shooting!
