Sure! Here's an example of a simple Space Invaders game using JavaScript and HTML, with the Mario invincibility star power-up. This implementation works on all devices, including smartphones. The game uses pictograms for the sprites.
You can copy and save the above code into a single HTML file (e.g., "space_invaders.html") and open it in your web browser to play the game. Use the left and right arrow keys to move the player and try to avoid the invaders. If you collect the Mario invincibility star power-up, you can destroy the invaders by colliding with them. Enjoy the game!
