Sure! Here's a simple game where you control a box and navigate through a maze to reach the end point. The game uses JavaScript and is implemented as a single HTML file. It is designed for smartphone operation and uses pictograms as visuals.
Note: Since this is a text-based interface, it may not work very well on some smartphone browsers. However, you can try running the code snippet below in a desktop browser to see the game in action.
To play the game, open the HTML file in your smartphone browser. You should see a maze displayed with a box emoji representing your position and a flag emoji representing the end. Use the arrow keys to navigate the box through the maze. Once you reach the end point, you will receive a congratulatory message.
