Just a couple of notes...
You do realize that for player 2 to insert coins he'll have to reach accross player 1 every time... (Until you have your full cabinet, that is...)
You're missing the Player 2 label...
(This is just a nit-picky thing...)
Where the smaller Pac-Dots meet the big ones at the bottom corners, there are smaller ones overlapping the bigger ones a little... It just looks odd... Maybe if you could center the columns of dots on the sides it could fix that... (It was just one of those thigs that caught my eye)
Otherwise you panel looks great & I'd keep the ghosts! (Maybe have 1 or 2 that aren't blue just for spontaneity's sake)
