Pokémon HeartGold Playthrough Part 17 - More Puzzles to Solve in the Ruins of Alph

Continuing from the previous video, here I am solving a few more puzzles in the Ruins of Alph. Also, some of the Puzzle Rooms have a hidden room after reading the Unown-written scripture, giving players a hint on what way to open it. For example, on the Route 36 entrance to the north, the first hidden room can be opened with the Escape Rope because that door reads "ESCAPE". As for the other hidden rooms, you need Ho-Oh, a Water Stone, and a Pokémon that knows Flash. I managed to open one of the hidden rooms with the Flash part. And collection all 23 Unown forms unlocks other lore and content within the Unown Report when talking to one of the researchers in the lab near the Route 32 entrance.
