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

NEW CONTENT:

• A new mansion?!

  Continue where the story left off in Mansion 2!! You'll get to explore the first half of this game's second act, facing off against... hey- what's that croaking sound?

• A settings menu!

  Upon starting a new game, you'll be presented with the option of changing a few settings around before playing.

• Screen filters!

  As part of the settings menu, you can enable/disable two screen filters: Vignette and Scan lines.

  You know, as if the game wasn't dark enough.

• Disable running and flashing lights!

  Want to play the game like the original Ao Oni? Want to play without getting your eyes demolished sometimes? All in the settings menu! (Most) flashing lights will be replaced with smoother transitions, while (most) chases will not allow you to run. Bye bye, shift key!

• Does the game finally have a title screen?

  Play a little longer and find out, compadre.

CHANGES/FIXES:

• Mansion 1's kitchen and living room have received visual overhauls.

  The assets were meant to look straight out of Ao Oni 1.1, but there are a few tiny changes to make them different.

  ... The crappy couches are still the same, though.

• Pinkarrion's back sprites are finished.

  Yeah, his back wasn't even shaded before.

• Keys are actually used when opening doors.

  Before, they just took up space in your "key items". I already knew that, by the end of the game, that inventory would be cluttered with dozens of useless keys, so now they disappear upon use.

• Loads of new sounds!

  Grunge asmr.

• Other bugs and grievances have been patched out.

  However... this does lend to one very big issue.

HEY THAT'S A LOT OF BUGS DUDE:

While I am very excited to see what people have to say about this version, I have to warn you all that Mansion 2 has some... unique mechanics that prop up maybe once or twice. Mind you, these have been play tested to heck and back! Buuuuut that doesn't mean that I found every single issue.

Expect quite a few small patches after this update, because I'll be there to fix them as soon as I can!

HOWDY:

• Are you thirsty?
