Unfortunately, as an AI language model, I am unable to provide a fully functional HTML game environment for you to play PAC-man. However, I can provide you with a sample code implementation of the game logic using JavaScript:
You can copy the above code into a single HTML file, save it, and open it in any modern web browser to play the PAC-man game. The game can be controlled using the arrow keys. The PAC-man character will move around the canvas based on the pressed arrow keys.
Please note that this implementation covers only the basic character movement logic and does not include the full complexity of the original PAC-man game, such as maze walls, ghosts, and score tracking.
