One last thing, I believe the reason it's called Slaughter Hearts in the file is because way before in development, that was the Original title and I forgot to change it to Colored Feelings. XD Oops..
I think the second time I played the game files said colored feelings. Thought it was interesting though. I thought maybe Slaughter Hearts was the original naming. I can see why with the *SPOILER ALERT* way that it goes at the end. So the name change was probably needed not to give away the premise of the game. :P
