It's a lovely game of discovery of the past with some tragic notes.
I like how the game length and the brightness of the scene can be tuned, but the thing that they are intertwined leaves me colder.
Although this is not explicit, I understand that the degree of success in the scenes is to be evaluated over the nature of the mission. If that is the case, this is my favorite part since the game varies widely depending on the initial choice of the mission.
I'll have to be direct in saying that the game lacks some bold element that makes me want to play it. Nonetheless, it is a very nice work.
