pretty solid map, especially the 4k set. I find this map very fun and the patterns fit well for the song. the only thing missing is the Svs. Since there are a few in the song, especially in INFINITE, it's rather odd for a song like this including svs that there are few of them. They could be unfinished but thats just me.
INFINITE: 00:01:300 (1300|2,1300|0,1300|3) - These triples should have some svs mixed in the pattern, but not anything too crazy, id use the same speed up and down method 1.40 - 0.60. be sure to put the second one in between the triples. leave the others alone since they'll do fine
00:17:299 (17299|2) - since nothing too crazy here, i'd add a slowdown with the svs, something like 0.90 or 0.80 and go back normal att 1.00 at 00:29:299 (29299|2) -
00:54:549 (54549|2) - this random jack came out of nowhere to be honest, i'd take that off or move it into a stair (Applying for EXHAUST as well) including the other random jacks as well
01:22:799 (82799|3) - these doubles should be like this personally

I like this map, but these changes should give at least an improvement in my opinion
Personally I feel like hard has some extra notes with these
00:39:540 (39540|2,39740|1,39940|2) -
these counting along the other notes followed up had it confusing for me with 00:42:940 (42940|1) - . basically leaving notes with the hard sound and bass should do it just fine.
01:58:740 (118740|0) - i feel like these are just out of the blue, but it also fits as well. I'd leave them be notes itself instead of lines
02:16:140 (136140|0,136273|1,136473|3,136673|2) - I like how you added these in, but two long notes would be just fine instead of four
02:36:340 (156340|1,156540|2,156740|1) - same with the beginning
04:00:340 (240340|3) - same with the other
overall i think its a solid difficulty
makes sense to see this but it feels like its incomplete with the last diff having hard sv slaps alone. if hard and insane had minor sv it would likely balance the entire mapset in my opinion, like a couple of 1.2 with 0.8 here and there, and keep the slow beginnings but slightly faster than pgs based on difficulty, like insane wit .80 and hard wit 0.9. just a thought :P
