there is one thing i noticed while looking at beatmania IIDX
the length of the song you used is different from the one used in the game. this is commonly called the full version of the song
the original beatmania IIDX 'ruin of opals' seems to have been used as a short version for gameplay, about 2 minutes long. therefore, we need to inform that it is the full version to protect the metadata of this game
so u just need to edit the title to change the song name in the metadata
current:
ruin of opals
new:
ruin of opals (Full ver.)
00:59:248 (59248|3,59304|2,59359|3,59415|2,59470|3,59526|2,59581|3,59637|2,59692|3,59748|2,59804|3,59859|2,59915|3) - after this performance, i recommend keeping the layout simple on the right hand
01:01:109 (61109|2,61192|3,61359|2,61526|3,61609|2,61859|3,61859|2,62026|2) - seems like its going to continue to be difficult like this
00:58:192 (58192|0,58234|1) -> 00:58:859 (58859|0,58887|1) - its best to avoid this to reduce the feeling of repetition for the same pattern as other sounds
00:54:692 (54692|3,54804|2,54859|3,54915|1,55026|2,55026|0,55109|3,55137|1,55248|0,55276|2) - it seems better to express this in just one
00:31:192 (31192|0,31276|1,31442|1,31526|0,31692|1,31776|0,31942|0,32026|1,32151|0,32192|1) - please create new strong patterns that are more reminiscent of the existing split structure
12-21-12-21, 34-43-34-43 these structures are really stxped lwl
00:28:359 (28359|0,28526|0) - its a little strange because connected differently from the sound
00:28:526 (28526|0) -> what about column 3?
i think its better to start cleanly like this rather than a very stacked layout
its better to continue with a uniform density in a monotonic sense since statistically didnt use the kind of transition you intended.
also, could give bonus points for including these irregular elements, but i dont want to put too much meaning into it (since the example didnt appeal to me)
i mean the unsnapping here 03:08:148 (188148|1,188148|3,188148|0) -, not LN at all
of course of this 03:07:720 (187720|0,187720|3,187734|2) -
