I was just re-playing Dear Esther, and was admiring the cave/underground areas. With the bio-luminescence, and soft candle lighting for contrast at parts...made the caves one of my favorite areas of the game to go through. The mist from the water also added wonderful atmosphere. My question is (or something to think of if you haven't already).......do you have any plans to add that kind of atmosphere to your caves?
And the sound...super immersive...with sound effects and music. Ok...now I'm gushing...and I must go play Dear Esther again
