Sure! Here's a simple game where you can control a red block and try to hit blue blocks while avoiding the other blocks. The game will be displayed as a set of pictograms, with JavaScript code enclosed in script tags within a single HTML file.
To play the game, you can open the HTML file on a smartphone or emulator and touch/click and drag the red block to control its position. The goal is to hit the blue blocks while avoiding colliding with the other blocks. The red block will bounce off the edges of the screen, and blue blocks will bounce as well. Collisions between the red and blue blocks will be logged to the console, but you can modify the code to handle them according to the game's rules.
Note: This is a basic template of the game, and it does not include additional features such as scoring, levels, or game over conditions. Feel free to enhance it based on your specific requirements and design preferences.
