None of them really mess me up, but i guess blink makes me lag a bit

You forgot about Blind/Ghost. :)
Also Speed+Blink is annoying but now I have conquered it, its just what Skull says, blink makes me lag a bit too.

Do you still remember the times b4 rotate was replaced, when rotate is hard as shit. Now blink is the hard one

Speed and blink are my doom.

Speed for sure

Blink ;-;

blink is by far the worst since every note blinks on a different interval so it's impossible to keep track of them

if blink applied to all notes instead of individual notes none would be particularly harder than the others (it'd also lag less since you wouldn't need timers on every single note)

Rotate was easy before the update that changed it, why it was changed? I don't know.

You forgot short.. (it takes less time for the arrows to get to the spots so basicly the arrows begin at the bottom of the screen.)

don't like wave d:

Both speed and blink really bothers me, but the combined one is way much worse.
