Cursed Clock Tower (3)

From the current room, go right to the next room and drop through the hole in the floor.

At the bottom of this room, hit the switch to open the way back to the clock tower.

You can optionally go through the newly opened hole to access a room via the hole on the bottom of the pendulum room for map percentage. Use the Bat Company soul to pass through spiked bars. In the next room's top portion, find a safe ground area amidst spikes to kneel and receive KONAMI MAN!

Otherwise, from the switch, head through the western door.

In the next room, which contains Golden Medusa Heads, a platform, and spikes, drop down to land on the edge of a spikey ledge (the eagle outcropping).

Drop from the outcropping to the door below.

The subsequent room has gears; drop straight through them, moving slightly away from the wall to avoid spikes.

Head through the left door after the gears.

In this room, head left, drop through the platforms, and prepare to use the Bat Company soul to turn into a bat and navigate through the spike-filled shafts.

Once you escape the shafts, continue right.

Hop to the box, then to solid ground.

Drop down through the platforms.

Get close to the wall (do not touch it) and slide under it.

Stand back up, hop over the spikes, and continue.

In the next room, a Devil will appear in the middle. Kill it to obtain its soul; this is the best room to take the Devil's soul for completion purposes.

Continue onward.

The next room contains Harpies. You can go back and forth between this room and the previous one to collect a Harpy soul. Three Harpies confront you upon entering, and one Mandragora should defeat them all.

At the far left of this room lies a door.
