Okay so hey, this is a suggestion not a big issue. But, i think you could make a better use of hitsounds by increasing the general volume of the map by 5%, i get why is the way it is now, but i think it could be something too check and then see if it feels good or sounds too loud. Imo it goes fine, but i'll leave that there.
00:21:318 (2) - How about making the slider linear? Think it would be cool. Because it's like some kind of easy back n forth like, you've already been there? Idk, just an opinion.
01:14:515 (4) - Think you could do a better pattern here? Like a Square, or make that circle closer to the next slider? Or moving it to where the circle 1 is. You could also try a small cross jump or X jump in this case, just move the circle a bit up and should do. Still, pretty nice pattern i just felt it rare when staring at it, but plays fine!
02:45:115 (1,2,3,1,2,3,4,5) - How about making them all the same combo ?
Okay so, i think you could 02:49:915 (1,2,1) - make these all the same combo so you can make this 02:51:915 (2,3,1,2) - a 1-2-12 instead od 2-3-1-2. Just something that imo, would be visually better when playing.
This one, i just a particular opinion i have but, 04:13:135 (1,2,3,4) - there are plenty of these. And i think instead of having the 4 a bit distanced of the 2, why not put it in the same spot? Let me explain why i think this would be a "decent" change. The diff is a Hard one, most hard players probably will be like "Why is it like this?" While i like a lot the pattern, it is commonly used on insanes (I could be 100% wrong since i don't play hards that much now). So, just saying it would be easier to read, and hit, and less confusing for most hard players. You can still refuse to change this, but take a look at if and check to see how it plays out. Tbh, is not a problem just something i felt could point out!
