hardest mod i have played is ofc Whitty with ballistic, hatsinu miku ( i dont know how to spell it ) and that scarecrow dude ( also dont know how to spell it )
tricky and mid fight masses i have played but were pretty easu
- this is my opinion on hard mdoe on any other mode week 2 is the hardest
easiest is tutorial
next easiest has to beek week 3 because there is nothing special and the songs are slow
week 1 is the next because dadbattle is hard for newer players
week 5 is next because this one part in cocoa which is for some reason very hard buyt besidews that easy
week 4 is the next because milf is the only hard one and most of it is fairly easy
week 2 is the next because some parts are hard in spookez but is possible
week 6 is my hardest because
1. the time in which you can hit the notes is much shorter so anything below good is not a hit anymore
2. changing the notes makes it slightly harder to see but not by much
3. roses and thorns has ALOT of notes and are fairly fast
( this is my opinion you may have others but these were the hardest and easiest for me )
