Arrow keys to move, so far
04/06/24 late to this, but i have a much better (and more finished) pacman project available in my account now -> https://scratch.mit.edu/projects/881835651/ I've only added PacMan and a ghost (Blinky) right now. Both have proper and accurate movement, though Blinky doesn't have the proper target set yet. You also can't die by the ghost right now and tunnels don't slow ghosts down yet. I plan on finishing this soon.
