Sure! Here's a simple WW2 game implemented as a single HTML file, using JavaScript and enclosed in script tags. Please note that this is a basic implementation and can be built upon to enhance the game further.
Score: 0
In the above code, we create a simple game where the player (plane pictogram) can move horizontally using the left and right arrow keys. The goal is to intercept and collide with the falling bombs (bomb pictogram) to score points. The score is displayed at the top of the game area. The game continues until you decide to stop or close the browser tab.
You will need to provide your own pictogram images for the plane (`emozi_all/pictogram.png`) and bomb (`emozi_all/bomb.png`). You can modify the code and add more features to make the game more interesting and interactive.
