Sure! Here's an implementation of the game as a single HTML file with JavaScript code embedded in script tags:
To play the game, simply open the HTML file in your web browser on your smartphone. The blue cube will move based on your touch events, and your goal is to eat all the black cubes by moving next to them. As you eat more black cubes, the blue cube will become bigger and faster. The game ends when you eat all the cubes. The current score is displayed on the top left corner of the screen.
