Sure! Here's an example of a simple drawing game using JavaScript and HTML. The game allows you to draw on the screen using your smartphone or mouse. It uses basic shapes as pictograms for drawing. Save the code in a single HTML file and open it in a web browser to play the game.
This code creates a canvas element that fills the entire screen. When you touch or drag your finger on the screen (in the case of a smartphone) or use the mouse (in the case of a computer), it draws a line on the canvas using the `context` of the canvas. The line being drawn is based on the position of the touch/mouse events.
Feel free to customize and enhance the game further based on your specific requirements!
