Don't bother, even if you like some of the artists like PilotRedSun. Bad design, bad voice-overs, bad gameplay, just bad. I know it's free, but still. You will get zero enjoyment out of this except a slight chuckle at how awful that Cats In The Cradle parody song was.
Come on, guys who made this. If this whole thing was one big joke between all of you, nobody else is laughing. I'm a big fan of PilotRedSun, but now I'm questioning him/her, because what person with actual talent puts there name on this pile of garbage.
Get it for the OST if you really want to, otherwise stay FAAAR AWAY.
