Sure! Here's a simple implementation of the Pacman game with ghosts and an invincibility star using JavaScript and pictograms. Remember to save the code in a single HTML file and enclose it in script tags for proper execution.
This implementation sets up the game environment with Pacman, a ghost, and an invincibility star. Pacman is controlled using the arrow keys, and the ghost moves randomly. The game loop checks for collisions between Pacman and the ghost or the invincibility star. If Pacman collides with the ghost, the game ends, and if Pacman catches the invincibility star, a victory message is displayed.
