If anyone wants the surprise spoiled, here are some vague notes on what specifically has changed:

• Pinkarrion's spawn rate has been set to normal.

  Admittedly, now he feels too easy... Hmm...

• Mr. Plate Shard can be used on a specific set of objects that you likely are familiar with if you've played already.

  Essentially, Ekzorzitz and Mr. Shard OTP.

• A special surprise that you're guaranteed to encounter!

  Meow!

• Improved graphics!

  By that, I mean some default assets have been replaced to fit with the rest of the game's "great art."

• Loads of new sounds!

  (I cannot tell a lie. Almost all of these new sounds were recorded about a year ago, but we all like to hide stuff, don't we?)

• Certain bugs and grievances have been patched out.

  If you find any more, please feel free to yell at me in any way!

• ... Wait, that's it? Anything else?

  All of these changes only apply to the mansion as it is. New rooms and new areas will all be mass added in the dreaded version 2.0!

• ... Can you show us anything about version 2.0?

  Nope!
