I really like the design and concept of the game as the graphics and details of the game made me feel like I was playing a game that I bought instead of a game for free. I liked the puzzles as even though they were quite confusing at first, I eventually figured it out, especially the third puzzle of the game. I completely did not notice the 3rd image on the bookshelf which wasted quite a bit of my time in terms of reaching the ending XD.
