The only issue I noticed on this map was the difficulty progression of the rhythms in the diffs.
Hyper feels way more dense than Advanced because it uses a lot of 1/2 rhythms ( if we count this song as 236 BPM for double BPM ) with large chains and on Advanced have only 1/1 rhythms with no 1/2 being introduced.
I suggest to buff rhythm density on Advanced a little bit, using more 1/2 acvive rhythms and 1/2 sliders, making a 2 or 3 object chain.
