Sure! Here's an example of a simple game called "Sneaky Maze" implemented as a single HTML file using JavaScript and enclosed in script tags:
Sneaky Maze Game
In this game, the player is represented by a red square, and they need to reach the green square (exit) by navigating through the maze. The maze is defined as a 2D array, where `1` represents a valid path, and `0` represents a wall. The player can use the arrow keys to move in the maze. If the player successfully reaches the exit, a congratulatory message is displayed.
Note: To play the game, save the code as an HTML file and open it in a web browser on a smartphone. You can also customize the maze by modifying the `maze` array.
