Simple Maze Game (Pac Man Style)

Hi

I wanting to create a really basic pac man style maze game, its actually for some marketing materials and it will be really used as means of navigation rather than as a game, I want pac mac to eat certain words and when that happens it will tell the user about that topic.

I don’t need ghosts or anything like that.

Just wondering what the best way for pac man to work his way around the maze would be?

Would I be best using hit detection?

Also what would be the best way to remove the pellets as he eats them? visibility or remove child?

Any tips / advice will be much appreciated, I’m still very much learning as3 and this is the first time I’ve attempted anything like this.

Thanks in advance…
