I finally got to modding this.
[General] - I think [Hazelz] / [Hard / [Normal] could benefit from Tick Rate 2, the sliders feel less empty and the ticks restore some HP during sliders.
- The difficulty gap between [Hard] and [Normal] is fairly large, optimally [Hard] would be a bit easier and [Normal] would be a bit harder. Just something to keep in mind for the future, I think this one is decent as it is.
[Hazelz] - Could you possibly rename this to [Insane] or something like that? It has a lower star rating than [Hard], so you want to make it clear which one is more difficult.
01:04:687 (7) -
Justice Breaker couldn't get ranked for a slider really similar to this one, so maybe try a shape more like
this? It also blankets (1).
01:15:675 (4) - This note goes into the HP bar some, so maybe just change the position a little.
[Climbb & Kana's Taiko]00:00:501 to 00:06:082 - I'd really suggest mapping this part, it's mapped in the osu!standard difficulties and most taikos I see seem to not have a "Skip" button at the beginning.
[Normal]00:27:443 - The placement of this inheriting section causes the spinner to suddenly drop in volume while spinning, try to fix this in whatever way works best for you.
[Easy]00:47:419 (1) - Here the spinner starts 1/2 tick after the previous note...
01:24:309 (1) - ...and here the spinner starts 1/4 tick after the previous note. This could be intentional, just making sure.
[Hard] looked fine. Just PM me after fixes and stuff.
