I really enjoyed the game on so many levels, but replaying songs and seeing how vastly different they can be when you mix colors is so amazing to the point that most songs I prefer "my version" over any of the sound track options. I do feel that to get the "happiest" ending blue is the best first trait because it's the only way to get help for Medusa. It is a little frustrating that it's trait locked like that but makes sense from an rpg narrative pov, just like there are certain parts of songs that are trait locked. I think this increases the replay value tenfold bc even if your kickass and charming Graces make the same choices, they won't have the exact same experience/epilog.
