Sure! Here's a simple game called "Furniture Jumper" implemented in a single HTML file using JavaScript. It's optimized for smartphone operation and features pictograms for better visual representation.
To play the game, save the code into an HTML file, open it in a web browser (preferably on a smartphone), and start jumping over the furniture. As you continue, the game's speed increases, making it more challenging. The score is displayed at the top right corner of the screen. If you collide with a piece of furniture, a game over alert will be displayed with your final score, and the game will restart after clicking "OK" on the alert.
Remember to always exercise caution when running code from unknown sources.
