The Doll's Window announcement

Thank you for playing The Doll's Window.
Today, I would clarify some details in the game.

• The flickering of the screen in the area below is intentional.
  
• The screen flashes, along with the red tints, reflect Alva's emotional state.
  

However, this effect might cause strain to the eyes during extended gameplay.
To lessen the discomfort of longtime playing, I provided the solution to the puzzle in this area below.

• Make sure to grab the key that's in a room right before this map.
• Avoid walking on the areas highlighted in pink.
• Make sure to grab the key, noted as a blue square on this map, before progressing.

I hope you'll continue to enjoy The Doll's Window.
