## What is SKETCHBOOK?

Every page remembers.
Step into a forgotten sketchbook where childhood memories, hidden secrets, and psychological puzzles are intertwined through beautifully hand-drawn graphite illustrations.
As you uncover one page after another, you'll explore abandoned documents, mysterious drawings, forgotten photographs, and long-buried memories. Every puzzle reveals another piece of a story that refuses to stay hidden.
Nothing is explained directly.
Every answer must be discovered.
Features
• Solve handcrafted environmental puzzles inspired by forgotten memories.
• Explore beautifully illustrated graphite sketchbook pages with a unique hand-drawn art style.
• Piece together psychological clues hidden inside documents, maps, photographs, and children's drawings.
• Discover an emotional narrative told entirely through visual storytelling.
• Atmospheric music and immersive sound design that enhance every moment.
• Relaxed gameplay with thoughtful puzzles designed to reward observation rather than reflexes.
• A mysterious world filled with symbolic details waiting to be uncovered.
Every object has a purpose.
Every page hides another memory.
Every drawing brings you closer to the truth.
Will you uncover what was locked away?
