After the almost unanimous praise received by the album "Decipher" and the perplexities raised by the new musical direction of the EP "Exordium", there were great expectations for the new album by fans and specialized press alike. The complexity of the music and concept of "Invisible Circles" produced mixed reviews, ranging from highest praise to complete failure, even in the same publication. The bold move of making a concept album about such a controversial matter was generally appreciated but, as Eduardo Rivadavia said in his AllMusic review, this could be a "slightly overambitious creation". The Maximum Metal reviewer states that "concept albums are always hard to pull off and not many bands can do it well" and "here is another failed attempt".
