This HTML file implements a basic Pac-Man game using JavaScript and pictograms. The game board is represented as a grid, and the Pac-Man and ghosts are represented as colored circles. The player can control Pac-Man using W, A, S, and D keys (or arrow keys) to move it around the board. The objective is to eat the dots (represented by the black cells) and avoid colliding with the ghosts. The score decreases by 1 point for each collision with a ghost.
Note: This is a simplified version of Pac-Man and may not include all the features and mechanics of the original game.
