When You're Gone explores through gameplay and motion comics the feelings of love, but more importantly those of loss and loneliness.
I like the Purple-Black contrast in the 'Shrine of the Drowned memories'.
As expected from Drunken memories it is dark and hazey with small luminant lightsources.
Small luminent sources of light is ideal for such a memory, seeing that people often drink at night making the only possible lightsources lightbulbs, stars or maybe candles.
It is also important to note that these lightsources are not depicted as lightbulbs etc, but as small wisps making the area seem like a magical forest.
Making a hazy "magical forest" doesn't only depict that Sam has lost himself in a forest, but also to enhance the concept of him trying find something in a forest.
Just like a certain memory in the back of your head, in this case the memory of Emma's perfume.
Sam himself seem to be afraid and insecure about what is going on, which is probably safe to assume.
I think it's important that you've captured the fact that he's a normal dude with normal dude problems, it's important that people can relate to a character when the game is about feels and deep stuff.
Keep up the good work!
