Completion bonuses: Successfully complete the game. Reset the game after
the ending. Begin game play with your cleared saved game file
and defeat the last Boss again. Reach the part where you can move
around Saint Mark's Plaza during the ending. Talk to the man
near the entrance of Saint Mark's Temple to get a key. Enter the
temple by using that key. The development office is inside. You
can also donate $66,666 inside the temple to unlock the "Visual
Mode" option.
