According to Jason Scott
from textfiles.com, Andrew Spencer
worked for six years on the game prior to its release.
Estatica uses an interesting software 3D "ellipsoid" technology that renders objects and characters completely using filled spheres/ellipses. The highly-optimized rendering algorithm performs automatic Gouraud shading and z-buffering, so the spheres are lit correctly and mesh together without noticable artifacts.
The word "Ecstatica" comes from New Latin and from Ancient Greek (ekstatikos) and one meaning is "A woman perceived to have a highly sensitive emotional state, or prone to quasi-mystical trances." And here it fits perfectly because the woman you rescue is named Ecstatica and is in a state of trance during your adventure and all her nightmares and visions come true in Tirich.
