Shop Lifter: The Five Finger Discount
A stealth focused game. At the start of a level it will tell you the name of the level, a password (use this to return to the level at a later time), what you need to steal, and what to watch out for (for example, steal candy bar, watch out for store clerk). Use your arrow keys to move around, and press the space bar to steal an item. Once you've got the item you need head for the exit - but make sure that you don't get spotted stealing. Watch the patterns of movement of hazards, and watch the cone that comes out from them - this is their field of vision; sneak in and grab things in the brief moments you're not in their field of vision. Stealing is fun!
