"We had put it in our head that, when people play this, there will be a lot they won't be able to see, but we don't know who is gonna see what. It is a little bit frustrating, but in the end we needed to make sure that no matter the path you choose, it was a satisfying path, that it worked, and that the player didn't feel cheated. We couldn't have a version that only lasted an hour, for example."
"That took a lot of structural work, to map all the options out really, really carefully. We used a very sophisticated software for that, with something of a 3D map, and that was a feat on itself, to make things happen. We also had to populate those areas with gameplay, dialogue, action... It was a lot of work. In the end, I would say nine hours is a safe bet for the first playthrough."
