45 hours! Really!?
With that much time I obviously have to compliment it:
I'm not sure about the beginning but afterwards it really sounds like RPG music.
The best part of it was when it really got upbeat and more tense.
I'm not much of a music critic but I'd have to say that the worse part was when there was the random part after the first pause which had little piano in it;
it didn't sound very good.
Otherwise, the rest was great. :D
