In case you haven't played a game styled like this, here are some tips.

• Interact with everything. In this game especially, the bookcases hold valuable infomation, which could also lead to achievements. A stone unturned is just a stone, but the key it could be hiding is worth the effort.
  
• Basic character controls (i.e. arrow keys, space bar for interactions, 0 on the number pad to access menu, etc.) No need to open your inventory to use items, though. It will do so automatically.
  
• Save frequently. This is a game in which dying is very possible and far too easy. Saving isn't just a means of "Time to sleep, need to save and go," but rather important, as there are chase scenes, things that you wouldn't think could hurt you, that do, and plenty of other bumps in the night that make saving so important. There is also an achievement for saving a certain amount! Check the achievements section for that.
  
• Take advantage of your multiple save slots. You will need to make decisions in this game. Make sure you don't need to start from square one every time you want to reach a new ending.
  
• Reference this walkthrough as often as you need to! There is no shame in it, as it will walk you through both yur directions and your actions.

And an important notice! This has been brought to my attention by a comment below and by my own playthroughs on another account. The codes CAN change, depending on the account. I've pplayed through this on my friend's account and the first code you come across varies for each account. My theory is that it is generated upon purchasing the game, so as to make it more difficult to follow a walkthrough. This may also be true for other codes throughout the game.

This walkthrough gives directions that tell you how to find the answers to things if you are struggling, with the codes themselves hidden until you want to see them. If the code is different for your game, follow the processes in this walkthrough to find them.

Again, this walkthrough is here to add to your experience in this game. You should definitely refer to it if you get stuck, but half the fun of playing this game is the satisfaction of solving the puzzles yourself.

As I stated in the tips section at the beginning of this walkthrough, the codes vary for each game. The code below was mine, and there is a chance it could be the same for you, but use the hints placed around this area to find your code.
The bookshelves in the drawing room provides the pattern hint for you, and the note on the wall next to the door that leads into the area has the blood-stained hint. The numbers on the left start the pattern, and the numbers on the right complete the pattern. Now, you just need to figure out what it is, and the missing numbers in the middle are your code.
My code is 2781.

Ending: Going In Circles

Really, Going in Circes is Rebirth Part 1. You need to have done all of this for Rebirth to be possible.

The only differences you'' notice in Rebirth that you didn't in Going In Circles would be the following:

• You team up with Ian to explore the mansion rather than Lilin.
  
• You can't make a decision when walking by the balcony, as this is essentially part 2 of a two part ending, and you have already made your decision by this point.
  
• You can't be teased by Lilin by the maid, as you are with Ian.
  
• The maid does not have a quest for you, as you have already done it.
  
• When you encounter Lena, She does not want to play with you. Instead, she says good bye, and thanks you for paying with her so many times. (SPOOKY HUH?)
  
• In the hallway where spikes emerge from the floor, the man you previously encountered in the hidden room is now your save space, and questions why you do not remember him.

From the point where you and Lilin encounter the evil spirit, and you and Lilin became separated, the story takes a turn.
Ian and you flee into the previous room, and the floor collapses beneath you.
Watch the short cutscene.
Delilah is seriously injured.
You are now controlling Ian.
Save with the man.
Interact with the sign on the wall above the crystal.
Go down the stairs that appear at the bottom of the screen.
There are five large Tombstone looking things with crystals that light up. Interact with them in the correct order in order to complete the puzzle. Trial and error will solve the puzzle.
The solution is: The Only, II, Tarot Queen, Square, Leo.
The logic behind this is the amount of sides something has. The only would mean one, II is two, Tarot Queen is three (not entirely sure why), Square is four, and Leo is five (again, not sure why).
Go back and save with the man.
Continue down and to the right.
Move cautiously. There aren't walls in this room. You WILL fall and die if you aren't careful!
Interact with the slate to remove an obstacle that lies outside and to the left.

Interact with the slate at the top.
Some stairs now appear to your right. They bring you back to Delilah.

Pull both levers, which make a hole in the room to the left, and then leave.
Go down the stairs and save at the bunny doll.
There are flame spirits in here which deal damage and can kill. Move cautiously.
Make your way to the llarge stone balls on the right. The best way to move through them is as follows:
The bottom rock accessible to you should be pushed all the way right. The rock now accessible to the left and down should be pushed down. Turn right and push that boulder next. Continue to push down and then right and exit the stone maze.
Retrieve the sector slate, then go and save at the bunny doll.
Head to the bottom left of the screen and retrieve the shovel.
Return to the hole where the two levers were and dig up that hole that appeared, getting anoter sector slate.
Return to the room with the flame spirits and save at the bunny doll.

Go up the stairs and save at the bunny doll.
This part of the game gets super tricky, so pay attention!
Flip all levers as you see them, that's a rule for this area. And move quickly. Things WILL start moving when you aren't expecting it.
After flipping the first lever, you find a map in the middle of the room.
The numbers are the order in which they are applied to the code for the only metal door in this whole area, which lies in the middle of the room. You'll need to rotate it or look at it in different ways in order to get what you need out of it.
The rooms are as follows:

Interact with the furthest left bed and look under to find the silver key. Don't look under the other beds or you will take damage.
Leave the room and head for the double doors (middle left) and unlock them.
Read the note on the wall and then speak to the pianist. You can talk to the figures here, but nothing they say is useful.
Start leaving the room. Stop walking about three times or so on your way, but make sure to get as close to the door as possible.
A chase scene!
Head out of the room and run to the room in the middle with the metal door. Save at the bunny doll!!!!!!
Go through the little opening.
Interact with the crystal.
Watch the cutscene.
As soon as you can, run for the entrance.
Head to the door.
The rest of this is the ending for Rebirth!

Hopefully, you all enjoyed this as much as I did!

For the Achievements: CG Fangirl and Extra Content, save the game when it has finished the ending, and then from the main screen, load that file. You find yourself in a lavish hallway, decorated for a party. Interact with the characters for the latter achievement, and continue up the stairs and interact with the various drapes for the former achievement.

If you have any questions, feel free to leave a comment!
