It was a pleasant trip with a great ambiance, the opportunity to take different paths and experience new landscapes was very nice and made me want to play a second time. 
There was also a nice little surprise in the game folder which I don't want to spoil for others so I won't say anymore ! 
It makes one crave for the opportunity to discover more about this valley (and drive this train on the seaside as Amina wishes). Great work, thanks for the game :)
