Sure, here's a simple implementation of a 2D parkour game as a single HTML file:
In this template, you'll need to fill in the game code and customize it according to your specific game requirements. The canvas element is used as the game display. The `update` function is the main game loop where you update the game logic and render the game state.
You'll need to define `player` and `obstacles` objects with appropriate properties and methods. The player object represents the main character of the game, and the obstacles object represents the various challenges the player needs to overcome.
Feel free to enhance the game by adding more functionality, such as collision detection, score tracking, level progression, and more. Remember to enclose your JavaScript code within the `
` tags. Good luck with your game development!
