Okay, here is a basic HTML structure with a canvas element, which is often used for games.

Okay, here is an updated structure with separate CSS for better styling and a placeholder for the game's JavaScript.

Okay, let's set up the structure to handle textures (images) and sounds. We'll add placeholders in the JavaScript for loading and using these assets. You'll need to provide the actual image and sound files later.

Okay, let's try to make it more interactive with basic movement and gravity. This is still a foundation, but it adds some core game mechanics. You will still need to provide the actual image and sound files in the assets folders.

Okay, building something "mega mega podobne" to the original Mario requires a more structured approach with sprites, tilemaps, and better physics. This is a big step up in complexity.

Here's a significantly refactored structure. You must provide the actual image and sound files in the specified assets folders for this to work visually and audibly.

Required Assets (Place these in the correct folders):

• assets/images/spritesheet.png: A spritesheet containing Mario's animations (idle, walk, jump), Goomba, block types (ground, brick, question, used), etc.
• assets/sounds/jump_small.wav: Sound for Mario's small jump.
• assets/sounds/coin.wav: Sound for collecting a coin.
• assets/sounds/stomp.wav: Sound for stomping an enemy.
• assets/sounds/brick_smash.wav: Sound for breaking a brick block.
• assets/sounds/music.mp3: Background music loop.
