The movement speed seems a little fast personally, but from what I can tell you realistically recreated the pacman level, which is a really nice touch. I would have liked if the ghosts were a little bit bigger, and it would be cool if you implemented the actually ghost characteristics in the AI, or at least bound them to the actual grid (As someone who's made a first-person pacman before [https://shadowlightgaming.itch.io/hackade], its very possible). It also would have been fun if there was an animation when you ran into ghosts with a powerup, otherwise it was great!
