Riddle in Riddle BGM

Riddle in Riddle (Stylized リドル イン リドル or Lidol in Lidol) is an 18+ Visual Novel published by AST on March 30th, 2001. It retailed for 7,800 yen and was drawn by Satoshi Kiyama. Running on Windows95 and 98, the game lacks animation and voice acting entirely.

A summary of the game's plot can be found here.

It's not known why Revo composed for this but he is credited in numerous places; including in the game's material, the credits, and the opening trailer. Because this OST was never released commercially, none of the tracks have names and are simply BGM files in the game's data. Due to this, four of the Eroge games Revo composed for (櫻姫, Riddle in Riddle, GeNOME ～進化の遺伝子を探せ~, and シスターマーメイド) remain unrecognized in most of his discography lists.

All tracks composed and arranged by Revo.
