Sure! Here's an example of a simple Mario-like game implemented using HTML, CSS, and JavaScript:
This code will create a simple Mario-like game with basic physics and controls. The player character (represented by a red square) can jump using the up arrow key and move left/right using the left/right arrow keys. The game loop continuously updates the player's position based on their velocity and the user's input, creating the illusion of movement.
Please note that this is a very simplified version of a Mario-like game, and it lacks many of the advanced features and complexities found in a fully-fledged game. However, it should serve as a starting point for further development and customization based on your requirements.
