Sure! Here's an example of a single HTML file that implements a basic stealth action game called "Stealth-Man" using JavaScript and pictograms:
Stealth-Man
In this example, we create a simple game canvas with a player represented as a black rectangle (pictogram). The player's position can be controlled on a smartphone by tapping on the screen, causing the player to move horizontally. You can extend this game by adding enemies, obstacles, and more complex game mechanics using additional JavaScript code and pictograms.
Please note that this is just a basic example to illustrate the concept and mechanics of a stealth action game. In a real game, you would need to handle collision detection, scoring, level design, and other elements to create an engaging gameplay experience.
