A guide about achievements and the puzzles.
 
 

General Information

Game Length: If you want to figure out everything by yourself I guess that would be a good 3-5 hours.
 
Required Walkthroughs: 2 at least, as you can unlock Emily or Chris related achievements based on the character you playing.
 
Chapter Select Avaialble: Yes, you can select a start point, so you don’t need to start from zero if you wish.(require to finish previous puzzle at least once to unlock the possibility to start with the new one)
 
Expected Perfection time: Even if it require to replay the game from the perspective of the other character (and probably twice again for each of you for the perfection achievements), these extra walkthroughs means just like extra ~1h as you already familiar with the puzzles and the solutions. Therefore perfection is about 4-5h, but if you use a guide from start then I believe it can’t take more than 1-2hours.
 
 
 

Library

Emily needs to find the note in the library that can be in different positions. In that note there will be 4 book names that you will need to communicate to Chris. Then Chris needs to choose the symbols out of the 12 available books that most closely match the book names.

Office Room / Clock Puzzle

Chris Hunt

 
Chris needs to find 2 clock arrows in the room and use it on the big clock, one each time. The bigger represents the minutes, the smaller represents the hours. Some shapes are projected via the projector and you need to tell about these shapes to Emily, who can translate these symbols to hours and minutes. DO NOT use both clock arrows on the clock at the same time, as both symbols, related to both the hour and minutes will be shown.
 
Chris also needs to set the time on the leftern clock.

School

Chris Hunt

 
Inside the school room there is a 5*5 grid, which activated once Chris using the VHS and playing it via the VHS player. It tells the rules of the grid puzzle: You can go straight and you can turn ONCE while trying to reach your target, but only ONCE, if you change direction twice, then the puzzle is failed and you need to restart it.

Greenhouse

Chris Hunt

 
Chris has access to a book which provides information about some flowers. There are 4 pots in the greenhouse, each has a name plate next to them. The user controlling Christ Hunt needs to provide information about the location of the pots and the details from the book. What kind of details are those?
 
 

 
 
Lets see that in this example, Callosita Viridi.
 
 
First you need to share the liquid colors and amounts, then you need to find from the description the keyword, in this case they are: parasite and poisonous. Then you need to set up the solution using the index at the robot controlling terminal. Both character can see this index, more details at the solution part.

Help Solve Greenhouse Puzzle
 
 
Green Thumb
 
Help solving Greenhouse Puzzle without ever making a mistake
 
 
To get this achievement you need to solve the Greenhouse puzzle without any mistake. This is the only “perfection” achievement which is earned as Emily.
 
 

Solution

 
 

 
 
As you can see on the index each keyword has a color combination. The keywords combined together that way, that the last color is shared with the first color of the next keyword. Callosita Viridi, from the example, is very easy, because it has only 2 keywords, each keyword consisting of 3 steps, but because of the merging of first and last colors it ends up as a total of 5 steps instead of 3+3=6!
 
 
Fortunately, this part of the game is not randomized(if that changes please tell us:-D), so the solution is same on every single walkthrough, and these are the following:
 
 
Pallas Ardesi
 
Purple -> Blue -> Purple -> Green -> Yellow -> Green -> Red -> Yellow -> Yellow
 
 
Locustar Tossicus
 
Red -> Yellow -> Purple -> Blue -> Purple -> Green -> Red -> Green -> Red -> Yellow
 
 
Callosita Viridi
 
Purple -> Green -> Red -> Green
 
 
Arbulae Tempus
 
Green -> Red -> Blue -> Green -> Red -> Yellow -> Yellow
 
 
 

Dinning Room

Emily needs to take the nameplates out of the cardboard box and put them on the corresponding portraits. You will know you placed them correctly when all nameplates are placed and you can’t remove them anymore. Looking at the portrait titles, you need to figure out the sequence for how to correctly pour the wine. Once you figure out the proper sequence, tell it to Chris who can then go on the second floor, to use the key to unlock the button panel with which he can execute that sequence.
 
 
The position of the nameplates on the table is randomized but the sequence is always Emily Wells -> Edward Mitchell -> Olivia Mitchell -> David Sandberg -> Lucy Finnick -> Simon Wells -> George Wells
 
 
Explanation for the sequence: James Pill doesn’t drink, so we will skip him, Emily Wells is his first one, she goes first, David Sandberg is a Don Juan, on the portrait he is accompanied with 2 ladies, the only remaining ladies are Olivia and Lucy, but Olivia and Edward are inseparable, that makes the order Edward -> Olivia -> David -> Lucy, Simon is a gentleman, that’s why he is near last and George is last because he puts the guests’ needs before his own.
