Okay, let's create a basic version of a challenging game inspired by the "World's Hardest Game".

Okay, let's add 10 levels to the game. We'll define the level data in the JavaScript file and add logic to load and transition between levels.

Now the game has 10 levels defined in levels.js. When you reach the end zone of a level, it will automatically load the next one. If you collide with an obstacle, you restart the current level, and the death counter increases. After completing level 10, a "YOU WIN!" message appears.
