Cornering, in the original Pac-Man game, is a concept where you can turn a corner at a 45-degree angle if you hold down the joystick while turning a corner. I've gone insane trying to reproduce this effect accurately. I think I've finally done it. It even works at high speeds. I don't know how. Don't ask me. Use arrow keys to move pac-man.
edit: found another issue! moves slower moving right and down... :( The only issue is that it limits the speed to one tile per frame. technically you'd never go that fast but if you have an improvement (code in pac center that does this) let me know or remix it or something I guess I could also make pac-man's center 0.5 pixels off because technically the bottom left center pixel is not the center of the tile
