This was a short but good soundtrack, the seamless transitions were so well done that I didn't even recognize that the track changed at times. I think my favourite track would be the second or the fifth track. "Traversing through the fog" sounds the most complete and musically fleshed out, while "Hiding in Quack Refuge" 's beat sounds pretty cozy.
Little nitpick, the instruments sound a bit pale sometimes, I got the "stock instrument" vibe at times.
