Hi , thanks for the comment!
I believe that ambientation is everything in a game like this, and I am very focused on achieve a very detailed ambiance.
The game is in a very early stage, so most of the ambientation guidelines come from concepts and story script, but I found that Unreal Engine 4 is just great to achieve the exact ambientation I was searching for.
We were making on this as small team in Unity before the UE4 release in march, but, after the release, I just couldnt avoid to decide the port of the game. I found that every aspect for the game feeling can be done with great quality without great suffering.
And, of course, sounds are very very important! To be honest, I would love to improve everything lots more, but… there is a long path ahead!
