It's really hard to rate this and it's DLC. Starts of with a huge sense of wonder and excitement, but in late game, everything becomes so tedious. Even if you get help from a guide which I did (yeah, fight me), I cannot fathom how some people discovered all these cryptic progressions by themselves. Even with those hints you get, some of which really tells you next to nothing or can be unintentionally misinformative. The ending is decent, though.
