Thank you so much for playing our game! I understand the ZXC being YXC issue very well, since we probably have the same QWERTZ layout. I believe our programmers have the QWERTY layout though. I also believe the person that worked on the rhythm section placed the notes by hand. We plan on improving some of the concerns you have though -- in our post-jam update. So if you want to play the game after, we'd be honored to have you back.
