This update would add some extra content while also clean up parts of the game. The challenges and FNATI night button will no longer be on the main menu. And instead be in a cozy little extras menu, the button for which will be where FNATI night is now. The extras would contain:

Full body renders of the characters

Jumpscares

The ability to replay the minigames (as well as the one marrowbot minigame from 1.0-3.0, although this is optional)

Rewatch all of the endings

Access the challenges (which are no longer in the main menu)

Custom Night (although this is also optional)

??? (aka FNATI night)

Tag #xuburextras for xubur to add this!
