Sure! Here is a simple example of a Pixilart game implemented as a single HTML file using JavaScript. Please note that this is a basic game and can be further enhanced and customized as per your requirements.
In this game, you control a blue player square using touch or mouse input. The goal is to collide with a red target square placed at random positions on the canvas. When a collision occurs, the target square is repositioned randomly. The game continuously redraws the canvas using the `draw()` function and utilizes the `requestAnimationFrame` method for smooth animations.
Feel free to modify and add more features to further develop this game based on your specific requirements.
