Wisdom Tree attempts to make a portable clone of The Legend of Zelda without accounting for the smaller screen size. Oh, how they fail.
Hidden Credits#
A room containing hidden credits can be found at the Beach (screen F9 on the grid map). Pushing the blocks in the position shown in the picture will reveal a staircase that leads to the room.
Since the game uses the same scripting engine on various platforms, this secret can be found in the NES and Genesis versions as well.
