Sure! Here's an example of a simple game similar to "Stumble Guys" implemented as a single HTML file using JavaScript:
In this simple game, you control a blue square (representing a player) using the arrow keys on your smartphone. The objective is to navigate through an obstacle course, similar to "Stumble Guys."
The game continuously updates the player's position based on the arrow keys pressed. The `gameLoop()` function is responsible for handling the game logic and calling itself recursively using `requestAnimationFrame()` to create an animation loop.
Please note that this is a basic implementation example and does not include a complete gameplay, enemy obstacles, or collision detection. You can further enhance the game by adding additional features and functionalities based on your requirements.
Remember to save the code in a `.html` file and open it in a web browser on your smartphone to play the game.
