Don't know if this has been mentioned, but Gamespot has finally posted an Indigo Prophecy review.

For those of you adventure gamers who read Indigo reviews just to judge the game difficulty:
"The thing about all these gameplay mechanics is that none of them are what you could exactly call difficult. Even if you turn the difficulty to the hardest setting, anybody with reasonable experience in rhythm games shouldn't have a tough time nailing down the faster flashes of the lights."
From Gamespy:
"Gamers looking for a challenge might be put off by the ease of this game, but you really have to think of the gameplay as a means to experience the excellent story."
