Thanks for playing it!
In regards to the game freeze and the score, they were both implemented late so I didn't have time to polish it. The amount of time that the score takes to tick up can be adjusted so I'll shorten that when I can reupload.
The feedback for the note we were going to have a sound effect but time restraints. I also wanted to add indicators for how good your hit was above the hit marker. Poor, Good, Great, Excellent, and Perfect. In terms of the misaligned gamenotes, I have a sync feature but didn't have time to put it in an options menu.
The notes also were more of a last minute thing and I'll probably change it to a multi-track system. The problem I had with the multitrack was how much space it would take up but that can be remedied by making the notes themselves smaller.
Thanks for all of the feedback!
