Very nice ! Music, visuals and writing serve the ambiance very well. Assets appearing while exploring the area was a nice touch too.
Only thing that bugged me a bit was not to be able to move around the map with the mouse. At some point I had two characters on north east and two on west and it was a bit hard to select the zone on the south east, had to click on the small piece of the area that was over there. Maybe also being able to change the speed with keyboard could have been nice too to reduce movements of the mouse between the top right of the screen and the button to close event at the bottom.
