Sure! Here's a simple generative art game implemented as a single HTML file using JavaScript, enclosed in script tags. It is playable as a finished game and is designed to be operated on a smartphone. Pictograms are used to enhance the visual experience.
In this game, a canvas element is used to draw generative art shapes. The `generateRandomColor()` function generates random colors using hexadecimal values, and the `generateRandomPosition()` function generates random positions within the canvas. The `drawShape()` function draws a circle shape on the canvas with a random color and position.
The `startGame()` function is called to begin the drawing process. It uses `setInterval()` to call the `drawShape()` function every second, resulting in continuously generating and drawing new shapes on the canvas.
You can open the HTML file in a web browser, and the game will start automatically, generating and displaying colorful circle shapes on the canvas.
