The idea is very good, the implementation has succeeded. The Puzzle Level 1 is a nice challenge, because the many pieces fit by their form to multiple locations and differ only by the imprint. Level 2 is significantly lighter but no less appealing. The finished puzzle with building miniatures looks all in all very good.
Unfortunately, the quality of the pieces of the puzzle has remained below expectations. Many parts were not completely separated from each other and some are torn apart when cautious solve.
