Extremely pleasant electronic sounds, with very interesting progressive instrumental effects. The chord loop is perfectly consistent, and works fine. The start of the theme is very much in keeping with the style of video game OST, but when the melody starts to pick up, I had to read the fictional game's sypnosis to understand why. After that, the final lyrical part is all the more sweet and poetic. A certain amount of strangeness therefore, which is justified by the original concept, for an OST which fulfills its functions perfectly.
