For some above-average players, Hard can be still a little bit daunting.
I don't want to create a medium difficulty that is too easy as to disappoint them.
So it is my intention to create a Medium that is a lot less difficult than Hard while still proves to be fun.

1. In Normal, Advanced, Hard and Extra : I find combo 1,2,3,5 too bright. They make a bad contrast with the backgroung which is bright too, that's very annoying. Please consider darkening them a bit.

1. 00:29:205 (3) - I wouldn't put it under (1) like this, that is very ugly. o.o
2. 01:35:205 (1,2,3,4,5) - This stack is quite boring. Unstack them, that'd make the pattern more exciting ~
3. 01:37:872 (1,2,3,4,5) - Same here.
4. 01:40:538 (1,2,3,4,1) - And here as well.

1. Same HP drain rate as in Normal ? uh? Don't you think 3 is not enouh for this difficulty ? Increase it please.
2. 00:19:872 (2,3,4,5) - This difficulty is supposed to be a Hard, right ? So, you should avoid this kind of pattern in Hard difficulties. You may wonder why ? Because having return several times to the same note's spot is very confusing and not very intuitive at first sight (that's why they don't fit in Hard difficulties).

1. To match the other difficulty names, Rename it "Hyper" ?
2. 02:17:538 (1) - Why are you stacking this circle. That's weird I think o.o Unstack it ? o.o

1. 00:09:455 (8,1) - I don't like the way they are close to the slider, that breaks the flow given by the slider :/
   Consider changing the pattern ? Maybe like this :
   
   SPOILER

   
2. 00:41:872 (1,2,3) - Try to make a better blanket ?
   
   SPOILER

   

1. 00:29:372 (49,50,51,52,53,54,1) - ddkkddk ? Sounds better imo.
2. 00:37:872 (1) - k ?
