Alibaba and 40 Thieves

Alibaba and 40 Thieves is a Pac-Man style game. Your goal is to catch the thieves... while being chased by the Chief Of Thieves! You have to catch the thieves before they disappear in the bottom of the screen 'cause then they are transformed into a bag of money. The money can be collected for extra points. Occasionally four question marks will appear in the maze. If you catch one of these question marks you will be granted specialties like bonus points, double speed or invulnerability.
