Room of Clocks

The Room of Clocks is a 'level' which is simply a room full of clocks, as the name suggests. It is accessed by finishing Tower of Execution as Reinhardt and Tower of Sorcery as Carrie (and Cornell in Legacy of Darkness).

It leads to the character-specific boss after the character's towers, which is Actrise for Carrie, Death for Reinhardt and Ortega for Cornell.

After you defeat the boss, you will go to the Clock Tower.

Differences between CV64 and Legacy of Darkness
There are no differences between the version in Castlevania 64 and Legacy apart from what items are in the torches.
