strict 업적 정타이밍에 클리어하면 얻어지는게 맞나요? 그리고 normal, hard 구분없이 얻어지나요?

Hey, this game is really cool, but i found a way to cheese it without any skill required. You can just press both F and J at the same time on each note and it'll count as if you got it right... This kinda takes away some of the challenge. So maybe it could be fixed?...
