Sure! Here's an example of a simple "Scary Maze Monster" game implemented as a single HTML file using JavaScript:
Scary Maze Monster
In this game, the player will control a red dot (representing the player) using their mouse on their smartphone's screen. The objective is to navigate the dot through a maze-like path (not shown in the code) to reach the top of the canvas without touching the walls. If the player successfully reaches the top, a congratulations message will be displayed, and the game can be restarted by tapping on the screen.
Please note that in the provided code, the actual maze is not implemented as it depends on the specific design of the maze you want in your game. Additionally, the code only implements the basic functionality to get you started. You can enhance and customize the game further based on your preferences.
