I would like to add to everyone else, this is very sweet and well done; kudos.

Also, you asked for suggestions. I have only one at the moment.

Since I studied Pacman back in Highschool (in order to make my own DOS/Pascal Clone), I noticed one behavior right off that was very different from the original game:

That is, you have it right that the ghosts do not come out until a certain number of bullets are eaten. However, if the ghosts are killed, they come back within a short period of time, not bullet count.

Without this behavior, the game is much easier, since I can concentrate on getting large sections of bullets, then eat a super bullet (thus killing all the ghosts), then concentrate on getting any small sections of bullets.

But I'd like to repeat my appreciation of this fine gift! It's very well done.

Oh before I go, I think sound effects would be nice (but also annoying to someone else in the car, so make them optional if you do). I also like the idea of fruit and extra lives. All of these shouldn't be too much to add; I'm sure someone else will do them .
