So i was having trouble getting all the achievements and decided to go through the game files. After mindlessly poking around and not finding anything i eventually decided to search all the .rpy files for the Achievement.add function. And what do you think, the exact achievements i was missing in-game turned out to be missing from the code to.

Currently, it seems impossible to get the following achievements:

1. I can fix you
2. Free the beast
3. Roam and invite
   
4. Blessed be (for some reason?) (the hidden one)

And, by extension, Mental Illness (which can't be seen until you get it) as it requires the player to get all the other achievements.

I'm guessing these are still in the works so you shouldn't worry about getting them, but if you reeeeeealy wanted to then i gueeeess you could just write:

$ Achievement.add(achievement_ICanFixYou)
$ Achievement.add(achievement_FreeTheBeast)
$ Achievement.add(achievement_RoamAndInvite)
$ Achievement.add(achievement_BlessedBe)

in GAME_FOLDER > game > script.rpy somewhere after "label start:" and press "Start" once in-game. Just remember to clean your karma afterwards.

by the way i love developers that make their games completely open source xoxo

Additionally: i was using Notepad++ to edit script.rpy and the game didn't shut up until i copied "tab characters" from other lines and pasted them in front of mine and retyped the brackets. Hope that helps.

Also, i just figured out that this is probably the moment where you're supposed to get "I can fix you" (during day 2 bng scene)

There's so much to love about Halloween! I can't believe ya don't like it.
Consider me your official Halloween educator.
I'm gonna fix you, and get you celebratin' the spooky season!
