The "puzzle" genre itself implies hyper-casuality, and if it is not diversified in every possible way, it will not hold the player's attention. The music is really good! The GUI... A little weird. I don't know why, but I have this feeling. The silhouette of the puzzle itself is a bit difficult to discern. When I first entered the game, I didn't even realize that we were in a room. The game, unfortunately, is very, very long, and it is not possible to complete it in one or two times. Here are a number of ideas that will really make the game more interesting: One move for us - another for father or daughter. AI that will add a random detail to the puzzle will greatly speed up the game. You can add dialogues between them that will take place in the background. The story of the puzzle itself, which continues after each completed piece. That is, you collect a piece of the puzzle, a voice in the background tells the story of this picture, and the father and daughter comment on it. Hints from the game, richer sounds and effects will also make the game more alive. In general, the game is not bad!
