Sure! Here's an example of an easy maze game implemented as a single HTML file using JavaScript and enclosed within script tags:
In this game, the maze is represented as a grid layout created by the JavaScript function `createMaze()`. The player, represented by the green pictogram, starts at the top-left corner (cell: 1,1) and must navigate through the maze by using the arrow keys on the smartphone's keyboard to reach the exit, represented by the red pictogram in the bottom-right corner (cell: 5,5). Once the player reaches the exit, a congratulations message is displayed, and the game ends.
Please note that you will need to provide your own image files for the player (`emozi_all/player.png`) and exit (`emozi_apple.png`) in the same directory as the HTML file for them to be displayed correctly. Feel free to modify the maze size, style, and image files as per your requirements.
