I forgot to mention this in the video, so it goes in the description:
-To Unlock The Bonus Dungeon-
-You need to have gotten a GOOD ending once. This is any ending where you are able to leave the museum. Falling into madness or purposefully missing your chance to leave will not count, and you will not get a newgame+ save.
-Afterwards, play again using the newgame+ save and the stairs down will be at the end of the game.
EXTRA 1.05 TIDBITS: (Doesn't warrant a video of its own.)
Apparently A BUNCH OF BUGFIXES. ALSO, THIS DUNGEON IS NOW MORE LENIENT WITH VASES. (Specifically, you seem to actually GET ONE BEFORE YOU START THE BONUS DUNGEON. Which means no more one-hit wonder.)
