-You shouldn't really be silencing slider ticks unless it is absolutely nessassry as they help with the flow of the map, if you don't like the sound of the default one try and find a custom one that fits more
-'Remilia' and 'Remilia3' shouldn't need to be above 800x600, they can just be scaled up instead.
gowww's Easy:
-Looks like some of the sliders on this difficulty aren't snapped correctly, check 00:11:476 (5,1,2,3,1,2,3,4,5,1,2) (Also make sure to double check the rest of them in the difficulty just in case)
AndreasHD's Hard:
-Would be nice if you could make this difficulty slightly easier to help the diffiuclty spread of the mapset, it is getting close to 3 insanes
-Why have the combo colors different on this difficulty?
00:56:650 (8,9) - an odd place for a jump, it doesn't really fit with the flow of the music (as well as Breeze mentioning it)
01:39:906 (7,8) - ^
02:05:022 (6,7) - ^
Kana's Taiko Oni:
-I am not sure about the really short spinners, I would get a second opinion on those for taiko
Everything else looks ok, call me back after fixes and I will rebubble.
