So... Rhythm Heaven Fever just freaked out for me...

I played Built To Scale 2 almost PERFECTLY, only like two or three misses, get to the results screen, Try Again

Did it count my barleys as misses for some reason, did the notes I miss count as a GIANT mistake, or when I play another level perfectly fine than it's gonna say I'm terrible at the minigame when I'm not

Can someone please tell me what I did wrong (luckily it's just a replay for fun, the Try Again doesn't effect me)!?
