Balatro adds new card backs from Stardew Valley, Cyberpunk 2077, Slay the Spire, and Binding of Isaac, and they're all free
LocalThunk, the solo developer of Balatro, revealed on X that the Stardew Valley card art was made by Stardew creator Eric Barone himself. "Thanks for the great game LocalThunk, I'm honored that Stardew is included," Barone wrote in response. " I have to 100% the game now."
