Just a little suggestion, the whole map has 2 long handtrills (03:04:810 (184810|1,184810|2,184810|0) - and 05:18:557 (318557|0,318557|2,318557|1,318557|3) - ) and they all started from the left side. this has caused some players mindblock (like me), then they had to use Mirror mod for playing. I know these patterns are meant to follow the piano pitch, but I think doing so has already affected gameplay.
These are two different types mindblock I think, "can't play long handtrills" and "got mindblock on same patterns". What I want pointing out here is more of the latter, but because this pattern is handtrills, the mindblock issue is enlarged. At least for me, after mirror the pattern I was able to achieve significantly better performance.
