Lock'n'Chase/Walkthrough

Controls

 * Joystick: Use the joystick to guide Lupin, your thief, in any of four directions. Lupin will continue to move forward in the last direction he was instructed to move in until he hits a barrier.
 * Lock: Press the lock button to lock one of the gates in the bank. The walls of the bank are dark blue with light blue lines running through them.  Some of the light blue lines appear on either side of a corridor, forming a gate.  Pressing the lock key makes a gate appear between the last two light blue lines that Lupin has passed.  You can only erect two gates at a time, and you can't erect a gate where an automatic green wall is already closing.  If one or more cops get trapped between two consecutive gates, you will be awarded bonus points.
 * 1-2 players: Press either button to start a 1 or 2 player game.

Lupin
You are Lupin, the master thief. Despite being setup during your latest bank heist, you are determined to grab all of the cash in the bank before the cops can catch you. On each stage, you must collect every coin that litters the floor of the bank. Once you clear the stage of coins, you must still make it to one of the bank exits and escape, either on the top or the bottom. If you can, you can also grab giant bags of money that stun the cops with embarrassment if you manage to collect one. If any of the cops touch you, it's lights out. But you have one defense against the cops: gates. As you run through the bank, you can lock the last gate that you recently ran through (shown by two light blue lines on either side of the walls) and prevent the cops from following you. Use these gates wisely, and don't allow yourself to accidentally trigger a gate that will get you trapped!

Stiffy
Stiffy probably has one of the worst names in video game history. Innuendo aside, Stiffy is definitely the toughest cop in the game, and the one to watch out for. Like Blinky in Pac-Man, Stiffy is always on your tail. No matter where you go, Stiffy is determined to hunt you down by taking the shortest path necessary. Stiffy is also the fastest cop in the game, despite Speedy's name. He can easily overtake you by stage 7, so lock those gates when he's behind you and make him find an alternate route to catch you.

Speedy
Speedy is usually right behind Stiffy. He is the equivalent to Pac-Man's Pinky. Count on him to be on your trail, or taking some alternate route in order to cut you off. If you use gates improperly, Speedy is quite often the one trapping you in from the other side, so make sure the coast is clear ahead of you before you lock yourself in from behind.

Scaredy
Scaredy is similar to Pac-Man's Inky. Scaredy knows that he has a job to do, but he doesn't seem to be in too big of a hurry to do it. He moves slower than Stiffy and Speedy, usually letting them overtake you in a chase and hanging back behind them just in case. In general, you don't have to worry about him.

Silly
Clyde from Pac-Man is the closest behavioral comparison to Silly. Silly seems to simply take random routes around the maze. If he has a direct path to capture you, he may or may not take it, which makes Silly very unpredictable. Fortunately, he's about as fast as Scaredy, so he's pretty easy to outrun in a chase. Keep your eye on him, because he may surprised you.

Moneybags
After you collect enough coins in each stage, a money bag will appear in the center of the maze and remain there for only a few seconds. If you manage to grab the bag before it disappears, the cops will be so ashamed, they will start to cry briefly. You will begin moving before they stop crying, but only for a second or two. During this time, you can safely pass them, but the time is so limited, you're almost better off avoiding the entirely and using the reprieve to get a head start on them. The money bag starts out at 500 point each stage, and doubles in value with each consecutive capture in a single stage to a maximum of 4000 points.

Stage Bonus
In addition to the appearance of the money bags, stage bonus appear. These stage bonus change for the first ten stages. After the tenth stage, it will stay as the heart for the remainder of the game. Note that the stage bonus do not always increase in value. Two of them contain a very low value in comparison to the bonus that come before them.
