Sooooooo coooool!!!!! I loved this so much, it felt super polished! The visuals were amazing and the music as well, and thanks to how free you are in the way you can hit the notes, there is a lot of room for feeling cool and doing "tricks"! I especially enjoyed to just launch away the pin when the disc was covered by red notes - super fun!!
I saw another comment about it already, but I also think that having at least some kinda SFX feedback, for scratching the disc would make the player feel even more cool, but other than that, I don't have any complaints! Amazing work!!
