I really struggled to play this game as my hands can't do hard core dexterity platformers but I really fell in love with the dynamic song mechanic. Only when your character Quill flies, she will sing with the soundtrack. Because of this singing mechanic, it is one of the headiest most thrilling flight mechanics I've had. The controllers were so tricky for me to even become mildly decent. It's not a deep game and there's definitely a lot of missed opportunity due to the limited indie budget, but because of the sheer joy the flying/singing brought me, this is the most memorable title in the itch.io bundle.
