Welcome to a guide on how to get through the puzzles and get the endings of tomorrow won't come for those without ██████ . This will be broken up into the areas between different veils. The guide will sprinkle how to get the two endings (SILENCE and NOISE) within it, but I will give a deeper guide at the end of the post.

I recommend getting the SILENCE ending before the NOISE ending, since I feel that NOISE is the true end.

I'll try to also tell where all of the Card Packs are. These are NOT needed for anything other than more game lore. You can't even get all of the packs/cards in a single playthrough.

Leaving Ori's Hotel Room
Ori wakes up in the bathtub and must look for his Rosary to leave. go into the main room and grab the cup of Questionable Snacks from the closet to the right of the exit. Follow the lavender blood to the bedroom, and grab the Rosary next to the unmade bed. After obtaining the Rosary, click on the body in the middle of the room and search it to obtain a Card Holder. Open the Card Holder in your inventory to obtain the ID Card .

The Main Area and Getting a Friend
Ori should now be in a room with three doors to the bottom, a violet veil at the top center and two doors to the side. Interact with the veil, and then interact with the door to the bottom right. You need to find a way into that room and obtain a friend!

Enter the top left room and enter the bathroom to the left. Pick up the Razor Blade laying next to the bathtub, and then interact with the tub to acquire the Key Card floating in the water.

Return back to Ori's hotel room (bottom center) and go into the right bedroom. Eat the Questionable Snacks in your inventory and get an Empty Cup. Interact with the body on the floor to get a Cup of Blood.

Go back to the main area and approach the bottom right door again. Enter the left room, and your cup of blood will turn into an Empty Cup again! This will trigger a cutscene where Ori meets Rem and return his ID to him. Leave the room, and Rem will join your party. Time to go find some hotel freebies!

Getting Freebies and Leaving the Area
Between each room, enjoy the banter between Rem and Ori if you'd like. Enter Ori's hotel room (bottom center), enter the left room, and grab the freebies from the sink. Then, go back to the main area and enter the top-right room. Feel free to grab the Card Pack before going to the left bathroom, grabbing the freebies from the sink.

NOTE: In order to get the NOISE ending, you need to get all of the Indulgences. Click on the vending machine next to the violet veil TWICE, and Rem will buy Ori Indulgence: Triangular.

Enter the violet veil to proceed to the next area.

Interact with the violet veil and listen to a conversation between Ori and Rem before Rem leaves the party. Feel free to pick up the Card Pack on the left side of the area. Go into the top left room.

Top Left Room, or Sunday Class Lesson: Patterns
This is a memory puzzle. Follow the path that the violet and white Celestial makes, and then select which path you think it took at the end. You will repeat this three times. Answering any of them incorrectly will take you back to the title screen. If you want the Celestial to speed up, press enter.

If you do not want to memorize them for yourself, the answers are 3, 1, and 3 .

Answering the puzzles correctly will give you a flashback. After this is done, enter the top right room.

Top Right Room, or Sunday Class Lesson: Barriers
Here, you will have to interact with various objects. Note that the time limit only applies when interacting with objects, which will display how many seconds doing the action will take.

1. Turn on the light switch located next to the painting in the main room (-5 seconds)
   
2. Enter the right room with the four bags, and pick up the Card Pack if you desire. This takes no time.
   
3. Search Inside (-15 seconds) the top bag and receive EULI. Search inside (-15 seconds) the bag underneath that (second from the top) to acquire some Matches.
   
4. Return the room where you turned off the light switch and approach the halo directly left of the painting. Wear (-15 seconds) it.
   
5. Enter the room to the left to find a white creature with Rem's head in the middle. Interact with Rem's head and choose "set on fire" (-20 seconds)
   
6. Return to the room where you got the halo and switch off (-10 seconds) the lamp on the leftmost side of the wall.
   
7. Approach the violet pieces of paper now on the floor. Listen in (-5 seconds) and read some of Rem's writing. Then interact with it again to tear apart (-99 seconds) the papers and silence the static noise. After this, you will be teleported back to the main area.

FOR NOISE ENDING: Go to the vending machine next to the veil with your new EULI and buy Indulgence: Square.

Enter the veil and continue to the next area.

Rem is back! Interact with him, and he will tell you what is necessary to enter the next veil. Rem will join your party again. Bring him with you into the bottom left room.

Bottom Left Room, or Sunday Class Lesson: Light
This room is entirely dark, except for a bit of light illuminated around Ori. Here, you will interact with the black figures in the room to turn them white. Be sure to go against the leftmost wall and walk up and down it to find EULI. There is also a Card Pack near the bottom of the room.

Listen to Ori and Rem's conversations as Ori turns these figures white. When all of the figures have been changed, you will be teleported to the main area again. Now, enter the bottom right room.

Bottom Left Room, or Sunday Class Lesson: Light
Ori and Rem will enter a room that looks like a chess board, with blocks of static, a statue of the Conductor and a Celestial in the corner. The rules are in the top left on tile B8 if you would like to refer to them. Push the Conductor in the area you want, then place Ori where you want. When you think you have the answer, press the T key. If you mess up, go to the entryway you came in.

To complete the puzzle, place the Conductor on tile F7 and then stand as Ori on tile H6 .

When you complete the puzzle, you will be teleported back to the main room.

The Rest of the Area
This is optional. But you can enter the crack in the wall of the main area to get some more information on the world, some fun conversations between Ori and Rem, and get another Card Pack. Once this is done, return to the main area.

Go to the vending machine next to the veil.

FOR NOISE ENDING: Buy the Indulgence: Circular rather than the Po-ka.

If you would like, save your game before making your choice. The poem you get from buying the Po-ka is random, so you can go back to that save and continue buying poems to read every one.

Pick up the Rosary on the floor, and go through the veil.

Interact with the veil to try to figure out how to bypass it.

Interact with the vending machine.

FOR THE NOISE ENDING: buy the Indulgence: Cross. Take all of your Indulgences here. You will learn more about Ori's past with his sister, Mari.

Otherwise, you can buy the Card Pack instead.

Enter the top right door. Ori will leave, leaving you to play as Rem. From here, enter the top left door.

Here is a sequence of 3 Rem will enter a room to find Ori, who will take then a triangle door. Follow him through this door, or feel free to look at the cards in the right corner to find what the "correct" solution is. If you enter the circle door, you will be taken back to the title screen.

Same situation in this second room, but follow Ori through the circle door instead.

From here, the endings split.

You now enter a room that looked like the last with the colors inverted. Ori here will go through the circle door.

For the NOISE ending
This time, do not follow him, and enter the triangle door instead. You will see that you are clear for the NOISE ending if going through the triangle door takes you to a white area with square and cross doors. If you go through the triangle door and did not buy/take all of the Indulgences, you will be taken back to the title screen.

Through these next few rooms, enter the cross, square and square doors. If you choose the wrong doors again, you will be taken back to the title screen. The second room has a Card Pack if you wish to pick it up.

For the SILENCE ending
Follow Ori through the circle door. Even if you collected and took your Indulgences, following Ori will still guarantee the SILENCE ending.

No matter which ending you are going for, you will come to a room with a purple eye-like veil and statues on both sides. From here, you will have to play from Rem and Ori's perspectives and switch between them with the O key.

Note that Ori's is the one that looks more like a hotel, and Rem's is more grotesque.

From Ori's POV
Interact with the statue of a girl on the right side of the room. If you took your Indulgences/are going for the NOISE ending, Ori will remark that the statue looks like Mari . Take her Lantern, and something in the room will shift.

Go to the desk on the left side of the room and ring the bell.

Enter the left room and interact with the Puricas. If you are going for the SILENCE ending, then the left one should work. If you are going for the NOISE ending, then the right should work.

Go to the rightmost room with a statue and a sign that reads "Exhibit A - The Delusional". Interact with it twice and break it. Interact with it again to hear Ori talk about sacrifice.

From Rem's POV
Switch over to Rem and pick up the violet Objects on the ground. There is one in each room. Interact with them in your inventory as you pick them up.

I ran into a bug here where the object in the right room did not appear unless I had Ori go on his ramble about sacrifice after breaking the statue. If this happens to you, try interacting with the statue on Ori's side again.

Ori's POV once again
After switching and interacting with the Objects, go through the veil.

Here, the endings split.

To get this ending, do not buy/take all of the Indulgences, and follow Ori through the circle door at the end of the following sequence.

THE ENDING
Attempting to go through the veil will have a series of random messages and flashing images.

As you go through the veil, Rem will run ahead of Ori. If you try to interact with him, Ori will ask the Rosary what to do. Use the Rosary with R and select "What should I do?" Go up behind Rem and interact with him.

This will trigger a series of cutscenes until the end.

To get this ending, buy and take all 4 Indulgences found throughout the game, and then enter the triangle door instead of following Ori in the third room in a sequence. Look through the guide to find out how to do all of that!

UPDATE COURTESY OF TATSUYASUOU : To get the noise ending, you need to take your Indulgences in the order you got them. You can take them all together in the last veil. Thank you!!

THE ENDING
Once you go through the final veil, you should get a cutscene where Rem comes behind Ori. Run up the stairs with Rem at your side. Another cutscene will play, and Rem will be alone. Continue running up the stairs.

When back in the hotel, enter the bottom left room. Feel free to explore the hotel room and read the papers at the bottom right corner of the middle room. Eventually, enter the bedroom and walk into the noise-filled closet. A cutscene will play, and the credits will roll.

Here, you will be asked to "Close your ears" or "Listen in on the noise".

Choosing the first option will lead to a thank you and a talk from the game's creator, while choosing the second option will let you learn more about Mari .
