For me, it was very difficult with the previous layout; I only managed an A because it's possible to press all the buttons and still get a hit (yes, I cheated on my first attempt).
With this new layout, I still need to be careful, and even then I wasn't perfect, but the difference was huge.
7 new songs added! I'm still trying to iron out some balancing issues since some of them might be too hard. After that there will be no more updates to this little game. Looking forward to your feedback and thank you for your support along the way!
