After this scene, you'll enter the endgame and there will be two giant puzzles before you can get closure. All the puzzles you've solved before will seem small since this final puzzle is less intuitive. If you don't pay attention, you can easily get lost in this for hours.

How To Solve The Rail Puzzle
After the cutscene for chapter seven finishes, you'll see yourself in a room similar to the picture above. The first thing you have to do here is to get close to the machine and press the interaction button on it. Once you press it, a cutscene will show you a familiar lady as the main character is on the bed with her eyes barely open.
When the cutscene ends, the area will zoom out and you'll be able to see the giant puzzle on a level above you. Use the stairs on the left to get to the puzzle since the right side is blocked midway. Once you get to it, a cutscene will open a bunch of small lights and a door on the far right side.
To solve this puzzle, you have to use different buttons to move platforms and use the shadow form to press all the small buttons similar to the one shown above. The worse part is that the game doesn't give you a lot of clues to solve this.
Start solving the puzzle by interacting with the lever in the middle of the platform you're on. When you interact with the lever, you'll be able to control a certain cart on the right side. Press the button on the left side to move this object to the left twice, and then use the shadow form on top of it. You'll be able to press the button shown above after doing that.
Once you've pressed the first button, go back to the lever and take the same object all the way to the left side. When it's there, use the book on the cart to go to your shadow form, and you'll be able to press the second button. Make sure that you don't use the book on the platform you're on by mistake.
This will unlock the second cart that is a little bit farther away from you, but you can still control it from the main lever. After the cart is open, head to the lever and move the cart to the left once. Upon doing that, you'll be able to use the book on your platform at the very left to get to the third button to the right of the second one that you pressed.
When you press the third button, you'll be able to access all the platforms in the back line with the same lever. Interact with it and move all the rectangular objects to the right so that it looks like the picture above. Now, you have to move the two cards to the right, and they will make a slope for you.
Leave the lever and use the book on the cart near you to get the button shown in the picture above. At this point, you're getting quite close to solving this puzzle. After getting this button, move the cart close to you to the right three times, and move the cart farther away to the left once. This will let you get the button on the left side, which is the final button.
For the final stretch, simply move the two carts to the complete right along with the right platform touching the bridge near the door. You can use the book again to get to the door and head to the next room with a huge cutscene. This is truly the final puzzle of Iris Fall, and it'll take you a long time as well.
How To Solve The Final Puzzle
At the end of the cutscene, you'll see a huge line of puppets going through the rail on the floor. To progress, you have to put a stop to this line so that you can get to the other side. Make your way to the right and you'll see the paper doll puzzle. There will be multiple dolls on the right side that will have a certain amount of buttons on their body.
These buttons determine the number of times these dolls will multiply when you place them on the board to the left. For the first puzzle, you simply have to place the two dolls on any of the diagonally opposite corners of the board. As far as you follow this instruction, the first part of this puzzle should be easy to solve.
The second puzzle will have three paper dolls at the bottom with a weirdly shaped board at the top. These dolls will have one, two, and three buttons respectively. To solve the puzzle, place the doll with two buttons in the bottom right corner. Next, place the doll with three buttons on the left side above the edge.
Finally, place the doll with a single button in the spot left at the top left, and the third puzzle will be revealed.
The third puzzle will be the biggest and the hardest since it will have one doll with one button, two with two buttons, and two with three buttons. Place the dolls depending on the numbers in the picture above. Place the doll with one button in the position with the number one and so on. This will gracefully solve the final part of this puzzle.
As the line of dolls gets disrupted, you'll be able to access two rectangular platforms, but one of them will be broken. When you see the rail these platforms are on, you'll notice a special portion to the right side with a lever near it. First, get on the smaller platform and move it all the way to the left.
Next, get on the taller platform and move it to the circular portion on the right side. When it's there, you'll be able to use the lever to turn the platform around. Finally, move this tall platform to the left and put it in the exact position shown in the picture above. After this, you'll be able to use the book on the left side and get to the next floor.
After the cutscene on this floor, you have to go to the right side and get the triangular shape on the floor first. Head back to the bridge and put this shape in its spot on the far left. After placing the shape, you have to press the button and the left slope of this bridge will connect to the upper portion.
Once the bridge is connected to the upper part, head up there in your human form, and you'll find the circle shape button on the left. Take this button and place it in the slot beside the triangle, make sure you activate it after. This will move the bridge in the middle upward. At this point, you have to use your shadow form to go to the right side and pick up the square button.
When you have the square button, go back to your human form and activate the circle button again. When the bridge goes back to normal, place the square button in its place and activate it, allowing the shadow to get out of the place it's in. Once it's out, press the square button again, which will allow the shadow to go all the way to the left side.
The shadow will hold the shadow lever on the top left, and you can press the triangle button again to make the slope go back down. Use the lever on the left side and you'll be able to go to the next floor.
On this floor, you'll be able to pick up a bulb beside you as soon as you get up here. Fit this bulb in the holder marked in the picture above, which will lower the bridge on the right side. Head to the right side and you'll find another bulb and a holder. Place the bulb in this holder to shine a light and create a shadow.
Before heading up the shadow bridge in shadow form, take the bulb out of the holder on the left. You have to use this bulb on the holder shown in the picture above. After placing the bulb, use this shadow form to go to the far right and take the bulb from that stand. Once you have the bulb, use the book in the middle to come back to human form.
Head to the far left side and place this bulb on that holder, which will shine a light on both the main eyes. After this, you just have to move an object around to fit it in the shadow one last time. This will trigger a cutscene where you can pick up the book from the bed, and the game will come to an end with the final cutscene.
