In Doppelgänger you need to help Frank Blank to remember.
The game is a singleplayer arcade version of the Memory. On each stage identical pairs of cards have to be found. You are given only a certain amount of attempts. Too many misses will cause you to go "game over".
The amount of cards varies between the stages, rising slowly the difficulty. Each level has a specific theme for the graphics on the cards.
