Cards are found throughout the world of Anodyne.
While their primary function is to open Card Gates, examining them on the inventory screen can provide interesting insight into the personality and function of the cards' subjects.
There are 49 cards in the game, 48 of which go in your inventory (all but Card 49). The Card 50 glitch can make your card count reach 50. However, the 50 Card Gate still won't open, even with 50 cards.
Finding 48 cards earns the "Lots of Cards" achievement on Steam. (Description: "You found all 48 cards!")
