He said that this one area (the enlargement section of forbidden lab) is larger than both Obsidian hall and Doll house. He thinks the game can be special and intends to have longer production time, especially on this area because its going to be very unique. The level of detail is astonishing.

Creator also says he wants to do an RPG at some point.
