Graphics and animation are superb. The characters in Flashback were motion-captured and move very fluently. Every action from walking, to drawing weapons, to hanging from ledges is nicely done. The graphics are very imaginative and realistic even despite the weak color palette of the Genesis. Sound is nothing to write home about. Each level has its own set of ambient background noises with add to the eerie atmosphere.
Puzzles are present in every task you must accomplish in the game. The puzzles can be difficult but are logical and a joy to solve especially since you begin to identify with Conrad and his situation. Conrad is not here to save the universe but instead wants to regain his stolen memory, his identity, only to find out he is a pawn in a more universe-encompassing plot. Puzzles can range from simple things like throwing rocks to distract motion-sensitive cannons to more difficult things like preventing a reactor from blowing up a city or figuring out how to get enough money for a fake ID.
