The Cliffside Ruins are located on a high cliff far above The Mysterious Ruins. You can on go to it by Island Flyover but, you can access the Mysterious Ruins in the 3rd stage in Expert Archery Level and The Sixth and sixteenth stage of Swordplay Showdown. In Island Flyover (having unlocked balloons beforehand), the Cliffside Ruins will have a gigantic blue balloon with many smaller balloons inside it, as do many landmarks in the game.
Island Flyover Information:
- Daytime: “How did they build this all the way up here?”
- Evening: “The stone blocks are perfectly laid-- you can hardly see any gaps!”
- Night: “Ancient writing is chiseled into the rock, but it’s getting faded.”
