The game has a great and successful idea with the possibility of developing it as a game for one or more people. Since it is built on a real basis, it not only makes the game more interesting, but it also shows its educational potential. I have a feeling and hope that I will see the game in some other development phase sometime ;-)
What I also liked is the simple graphic design of the manual - simple colors, clear shapes. I would just like to describe the really simplistic versions first.
