Menu is so cool, and the ticking fits in very naturally. Save File Select is a banger, and somehow I could also see it working as a battle theme. Pretty ambience in The Center of Time. Time Travelling is a pretty cool build up using the chords of the previous track. Very groovy! Clash is an instant banger, and I love the 1-b3-2-b2 progression, its a very cool one to me that works great for battle themes. This battle theme make random encounters much more interesting lol. Culprit sounds dark in a way that perfectly fits the description you gave. Fateful Duel builds upon the ideas of Culprit while adding a brighter section to contrast, climbing up to that sweet dominant resolution. Great work, was an absolute treat to listen to!
