Alone in the Tower

From itch.io: You are the young heir of a royal house, trapped in a tower in the wilderness. Legends have spread of your predicament, and (if your tally marks of the days passing are correct) the prophesied day of your freedom is fast approaching... This is a solo tabletop roleplaying game. You'll need a standard 52-card deck of playing cards, a six-sided die, and some method of writing to record your story. This game is a hack of Takuma Okada’s Alone Among the Stars.
