On Kingdom Hearts when you play Sora as a Heartless, how do you get out of the Castle?

Answer 1

You will learn the Ragnarok ability for defeating Riku. Once you appear as a
Heartless back in the Grand Hall, return to the Lift Stop, and then head out
to the Castle Chapel. Continue into the Lift Stop, then to the High Tower.

The crystal console will not respond to you as a Heartless, you will need to
jump off the ledge to the Great Crest. From here, jump off the ledge to the
Castle Gates. Head down the path to the Lift Stop. Proceed into the Entrance
Hall to find Kairi, Donald, and Goofy.


Taken straight from a walkthrough. Hurry up and beat the game! Play KH2!!! It's LOADS better!!!

Answer 2

when you become a heartless after the boss fight head back to the High Tower area and drop to the Great Crest. Drop off a balcony to the Castle Gates below, then go inside and return to the Entrance Hall. Walk up to your party to shift control back to Sora.
