The Legend of Zelda: Oracle of Seasons/Graveyard and Explorer's Crypt

Compass

 * From the entrance to the compass

In the first few rooms there are no forks. Use a mystery seed on the owl statue. In the second dark room, go quickly to the right, or Link will be sent back to the entrance. Defeat the Wizzrobes ghosts in the next room and claim a small key.

With the key, backtrack to the door in the second room. Defeat the Stalfos skeleton and the red Zols, then claim a magic ring from the chest.

Follow the upper path, and at the end of it shoot two ember seeds at the two braziers. A Poe ghost will attack you with a sword, but the dark rooms are no more! In the room that was previously getting dark there is a cracked wall: blast it with a bomb and claim the compass.

Map

 * From the compass to the map

After getting the compass, go to the next room and go down the stairs. Ignore the Armos statues for the moment, and go straight to the west room. Press the button to create a trampoline, then use the latter to obtain another small key.

Back to the Armos room, one of them at random is a true statue: find it and push it on the button to keep the door open. Go two rooms south, where a trampoline is. The blocks on the two sides of the trampoline can be pushed: make an opening on each side so that you can push the trampoline to the west. In particular, move it three steps west and one north, then jump. The chest in the upper room holds the map.

Roc's cape

 * From the map to the Roc's cape

After getting the map, backtrack one room to the north and take the stairs down. Use the magnet glove in the first room and a Pegasus seed in the second one. You'll end in a puzzle room. If the top-left is n.1 and the lower-right is n.4, press them in this order: 2-3-1-4. You'll receive a small key.

Go back upstairs to the trampoline room, where you can now unlock the door. Use a Pegasus seed to gain speed and the slingshot with ember seeds to light the four braziers. The second Poe ghost will appear and attack with flames. After you defeat her, the dark curse in the west room is broken, and you can proceed to the deeper floor.

Believe it or not, the heavy armor of the Darknut warriors can be pulled with the magnet glove: defeat them, and a bridge will appear. Cross it, activate the magnetic spinners, then combine the magnet glove, the roc's feather and a Pegasus seed to get to the two trampolines. Jump on the red one first. Follow the path, that includes some hard jumps, until you get the Roc's cape.

Sub-boss: Poe Sisters

 * From the Roc's cape to the sub-boss

After getting the Roc's cape, go all the way downstairs, where the flying tiles bridge is. You have to get familiar with the cape so to perform two double jump on the east side of the room. Using the magnet glove and the cape, you should get to a chest with another small key on the 1st basement floor.

You're back to the Armos room; go all the way south, then west, then downstairs. Use the key to unlock the block. Wait for the flying tiles to be finished before venturing across the room. Follow the path, defeat the Moldorms, then use a Pegasus seed together with the Roc's cape so to reach the button.

In the next room, Link will face the Poe Sisters. Equip the sword and the slingshot with the ember seeds. If the ghosts manage to turn off all the fires, Link will be sent back to the dungeon entrance.

Boss key

 * From the sub-boss to the boss key

In the subsequent labyrinth of stairways, the chests holds just 1 Rupee. Use your memory and see which stairs connect to which so to get to the north-east exit from the room.

Once more, use the Roc's cape together with the magnet glove. Defeat the Stalfos skeletons and the Wizzrobe wizards so to get one more small key. After Link unlocks the door, use the Roc's cape with a Pegasus seed, so to press the buttons in the order that the sculptures hint at. Make the trampoline appear and go up.

The owl statue gives a hint so to solve the riddle right below it: only one globe should be blue. In the next room, you can get the boss key.
