This is an interesting map and id like to see what others have to say.
The beginning to me is kinda difficult due to it feeling kinda random? spacing and rhythm wise.
The first kaia has some rhythm issues because i cant really tell what exactly is being followed with the long sliders covering up most of the synth noises here, granted it being consistent through makes it better.
The section before the 1/3rd section is kinda neat but i think the spacing is a bit much with how soft that section is.
The 1/3rd section is really overdone with it being a soft piano and jumps like 01:11:736 (4,1) - being present at the lowest point, 01:20:827 (1,2,3,4,5,6) - while this is one of the lowest spacing but the highest points on the piano.
01:30:281 (1) - This is cool, neat pattern that does make sense here even with the spacing at the end. Good job.
The final Kiai overall isnt the worst, but like the other kiai there are rhythm issues due to not following the main piano part of this section, sometimes. Its followed every other quadrant of the first half.
The second half is a alright, but having the circles go back under the sliders makes it hard to read as its the only time this occurs in the map.
TL;DR its a neat map with a decent amount of rhythm issues, and i'd like to see improvement on it.
01:47:100 (2,3,4,5,6) - This is not a problem to read for expert players, and the reason there is nothing else in the map like this is because this particular section only happens twice in the song
01:34:281 (5) - Slider here because the sounds are less intense. 01:37:190 (1,2,3,4) - Stronger and circles
might wanna use tick rate 2 on this cuz on tick rate 4 the 01:09:963 (1) - to 01:21:478 (6) - section's sliders looks like it's gonna be annoying af to play
Overall really interesting map, a lot of it is just visuals, so watch out for weird and clunky overlaps in future mapping
