Pedro is a traveler making his way across a kingdom — solving puzzles, befriending locals, and defeating monsters on a quest to rescue a princess. His journey is also the player's journey into the Spanish language. Pedro's Adventures in Spanish is designed to run entirely in Spanish with no in-game translations, working for learners regardless of their native tongue. All interface elements, dialogue, and narration use simple Spanish supported by images, animations, and enough context to make objectives clear. Hovering over any object reveals its Spanish name. Characters can repeat themselves as many times as the player needs.
