Very charming OST you got here! Not only it is varied in genres but you've composed them pretty well and accurate to your settings! My favorite tho was Wistful Mistin' and second one was Quips and Quirks, the idea for a dialogue theme is great and the track really delivers! The least one that I liked was Cosmocats because it feels a bit bland compared to the other tracks. Overall I've really enjoyed listening to it, great work!
