broadly, it is really nicely done. Graphics great, completely German spoken, so also too lazy to read. The search images are relatively simple, because you sometimes have to look for the same items in an image usually 10. The puzzles you're one or the other busy times a bit longer. The sinking and being filled with water areas, or how to do this may delay, but then bring but one serving of tension in the game.
A big minus ... it's really played out in a few hours.
