General
"is" in tags ? Why ?
Add "heilpoint" and "climmb" to the tags ? I doubt people would bother typing their whole nicks.
Milk's Easy
I'm worried about the constant 1/1 parts. It might be quite tiring in the end (for new players) and makes the map somewhat repetitive.
00:39:091 (1,2) - I think this is quite confusing for an Easy, because a new player would probably expect the first slider to be 1/1, and panic when they realize it isn't. Just my opinion though
00:54:675 (1) - This is too far from the center of the screen and too soon after the spinner.
HeiL's Normal
Quite hard for a Normal, due to all the 1/2 patterns.
00:00:130 (1,2,3,4,5,6,7) - Pretty harsh for the beginning of the map. Some of these beats actually match nothing in the song, like (2) and (5) (and (7)). I think it'd be better to make this a bit easier. I also think it'd be good to reduce this combo length a bit, for example by adding a new combo on 00:01:493 (4,8) - .
00:10:259 (1,2,3,4,5,6,7,8) - This pattern is quite hard too. The second slider also feels misplaced (it should be 1/1 before).
00:14:155 (4,5) - Stack (5) with (4)'s end properly ?
00:39:091 (4) - If you wanted to follow the music's cymbals, this should end 1/4 earlier.
01:25:844 (1) - I think this is quite far from the center of the screen so soon after the spinner.
01:27:207 (1) - I don't think this new combo is needed.
Hina's Hard
Lots of added notes that make no sense with the song imo...
The hitsounds are too quiet.
00:04:610 (4) - Too close to previous object ? It plays fine, but it's the only spacing error in the whole diff =(
Insane
Way too many beats added that make no sense with the song... The diff feels like it was done for the sake of having an Insane diff in the mapset.
00:04:805 (1,2,3,4,5,6,7,8,9) - This pattern for example makes no sense whatsoever, and is actually confusing to play.
Climb's Taiko Oni
Lots of patterns look weird to me... But I'm not a taiko mapper, and I can't really mod taiko diffs ._. so I'll just say I didn't enjoy this one much :/
Not popping, but consider making these changes.
