Extase (Cryo, 1990)
From the same French team that produced Captain Blood and Purple Saturn Day, Extase is undoubtedly one of the most visually and sonically unique games on the Amiga. The interactive musical score by Stéphane Picq, Philippe Eidel and The Bulgarian Voices is frankly amazing. If you let the game roll in demo mode, it will cycle through many of the in-game tracks (I often have it running in the background while I’m sorting disks etc.) However, being an interactive score, the music is affected by the player’s input and is best experienced in game mode.
There are eight stages in which the player (or players – Extase is a 1 or 2 player game) must program the brain circuits of a sleeping female android through a neural network. Each stage corresponds to a different emotional state, with the final one being ecstasy (Extase).
