After you choose D-Team's Suppression fragment, you must escape the healing room.
Seek a Way Out
Go to the harpsichord and touch the keys. Take all of the white keys.
Find the desk to the right of the poster. Take the note, which shows an eye looking through a wine glass and pitcher at a star.
Take the tumbler from the desk.
Check the desk drawers to find matches.
Find the dial on the wall. Turn it to make the walls change to a flower design.
Find the flower poster on the wall. Touch the flowers to start a puzzle. You have to make all the flowers bloom. Touch the flowers in this order:
1-4- ---5 2-3-
Now find the black knife in the wall.
Turn the dial until the room is back to the checkerboard pattern.
Go to the poster that says "defeat me", equip the knife, and use it on the middle of the demon's chest. The console will turn on, and the screen says "Shoot more Keys".
Pull the lever on the bottom-right of the console. The cover will open. Take the digital camera out.
When the room is still in the checkerboard pattern, look at the wall to the left of the chairs, and you will notice that it looks different. Use the digital camera on it and it will turn green. A cover on the console will open. Use a C key on the hole that opened.
Now turn the dial on the wall until the room shows a forest. Go to the red tube and use the digital camera on the pattern inside, and another key cover will open.
Put the tumbler into the middle of the circular pattern on the floor. Then use the digital camera to take a picture of it. Another key cover will open.
Go to the candle between the chairs and use the matches to light it. Then use the digital camera on the candle to open another key cover.
Use the digital camera on the chair on the left and rotate the view until the shape on the headrest lines up with the shape on the wall. Then use the digital camera to take a picture.
Now put the keys into the holes that opened.
Turn the dial to make the room show flowers on the wall again. Touch the closed bud to open it. Use the digital camera on it to open another key cover. Go put the key into the hole.
Now turn the dial to make the walls show flying clouds.
Pour water into the wine glass and pitcher. Then use the digital camera on the wineglass, and rotate the view until the star is shining through the wineglass. Use the digital camera to take a picture. Another key cover opens.
Some shapes will appear in the wall. Use the digital camera on the shapes, but wait for them to rotate until they glow, then take the picture.
Now put all of the keys into the holes. Press the button to the left of the keys to play a tune. Make a note of the keys that were played. The keys all fall out after the tune is played, but you can press the button again to make the tune play again.
The tune is G, E, F, high C, low C, D, A, B.
Go to the harpsichord and use the keys on it to put them all back. Then play the tune that you heard in the console. In other words, play the keys in this order:
----1--- --2----- ---3---- -------4 5------- -6------ -----7-- ------8-
This will end the room escape.
After the room escape puzzle, you will have to decide whether or not to press the button. You have slightly more than a minute to decide. If you let the timer run out, you will not press the button.
