Sure! Here's an example of a simple 2D platformer game where you need to collect all the stars to complete the level. It uses pictograms and can be played as a finished game. Note that this is just a basic implementation and can be expanded upon or customized further:
To play the game:
1. Copy the above code into a text editor and save it with a .html extension (e.g., game.html).
2. Open the file in a web browser.
3. Use the arrow keys to move the player left, right, or jump (arrow up).
4. Collect all the yellow stars to complete the level.
5. If you clear all the stars, an alert will appear congratulating you for completing the level.
Feel free to customize the game further, add more levels, or enhance the graphics as desired.
