I did found a method were you go to properties, and from switching the "Run" option from Normal to Maximized. However upon opening the game it boots up as usual, However reopening it at the windows bar, does allow the game to open a nice wide screen gameplay of Jr.Pac-Man. HOWEVER, it shrinks back to its normal ratio during an intermission. So my suggestion would be to reclick the game icon from your windows bar, after the intermission. I hope this kinda helps, I sure do hope they'll release more updates.
