You are a gangster chaser. Your purpose is to annihilate gangsters in various ways: to throw down a stone at the gangster; to drop a boomerang, dynamite or a bomb; to shoot a gun at the gangster etc. The methods of gangsters' destruction change from level to level and become more complex. To rule the chaser you should use arrow keys. To perform various actions with subjects it is necessary to approach a subject from the certain side (the chaser's position will change) and to use the following keys: right or left arrow - to throw, push, switch; up arrow to lift, down arrow to pull down; the space bar is used in other cases (e. g. canon fire etc.) The higher level is, the quicker the action is performed. Good luck in chasing the gangsters!
