Sure! Here's a simple maze game implemented as a single HTML file using JavaScript.
Maze Game
In this game, you control a person (represented by a green block) using the arrow keys on your smartphone. The goal is to reach the blue closet without being caught by the enemy (represented by a red block). If you collide with the enemy, the game is over and a popup message appears. If you reach the closet, a congratulatory message is shown, and the game resets for another round. The maze's size is set to 400px x 400px, but you can adjust it as per your preference.
