Sure! I can provide you with a basic structure for a game like Mario but with a duck as the main character. Please keep in mind that this is just a simple example of how the game structure could be implemented, and you would need to add your own functionality, storyline, characters, and graphics to make it a complete game. Here's an example code enclosed within script tags:
Duck Adventure - The Game
Help the brave duck explore the world and overcome obstacles!
Please note that this is just a basic template for the game structure. You would need to add functions for player controls, collision detection, enemy characters, power-ups, and various storylines to make it a fully functional game. Additionally, you would need to replace the "emozi_all/game.png" with your own duck sprite and build on top of this code to create your desired game.
