very nice! pacman moves faster than ghosts in the original which made them awfully hard to throw off and you dont get cornered so much because of the less aggressive AI. good for first level difficulty since the arcade pacman tends to frustrate me lol. the pills seem to fade a bit too dark though.
I suggest you try to make a "physics-related" game such as arkanoid so that you get a feel for how to make a wider variety of games.
I was thinking that graphics were crappy because i did them and yeah it is easier than the original because bad guys are moving here and there randomly (though i programmed them to follow pacman but ... still they are dumb)
