Thanks, glad you like it! Yes it's pretty tight. Originally you used to have to just get lucky and hit exactly 100, which was basically impossible. So in the the 1.6 update (the most recent one) I put a special case for 100, where if your score is over 99.5, it just makes it 100 (internally note scores are calculated, and then rounded down to the nearest integer). So it's still very precise, but at least possible
