I'll Admit only played for a bit, the game is Decent and not to bad.
yet i had also noticed at the time in ch 1 during the time Culania went into Forest, i Recognized the song playing Dead spot on. it was Tir Na Nog area in Mabinogi (a Fantasy MMORPG), not gonna lie that was quite unexpected there.
Edit: okay i have finished the game and the story is amazing,and the factor of sound comment eariler. i noticed you added alot other songs from mabinogi in there, considering i recently got off it from event to try this out. keep up good work
