Labyrinth (Famicom)/Area 2: Hedge Garden
This is the first area in which space is actually warped. By standing on the areas indicated with the red letter, you will actually end up warping to the respective blue letter. These warps will not be immediately apparent, since the layout surrounding hedges are identical in each location. In the case of locations A through D, the warps only activate as you attempt to escape from the center without talking to the Wiseman.
Compared to the first area, the enemies here may be a bit more challenging to deal with since the passageways are much more narrow. To complete the area, you must travel along the bottom, and up the right side to reach the red E which warps you to the blue E. Then collect the coin, and take the time to collect the Labyrinth Book to the right of the red F before standing at that location to warp to the blue F, which will provide you with access to the area's key piece.
