The map is really very nicely done. But during the game it feels too loud samples/hitsounds. In the guitar solo some of the streams don't have a smooth combo transition for example here 05:45:909 or here 05:55:039. And it bothers me a bit that all sources state this track as being played at 182 bpm.
The beginning of the guitar sound, for example, starts at the beginning of the beat, in the white area. So this stream 00:02:747 (1,2,3,4,5,6,7,8,9,10,11) should start 1/4 bit later or earlier in this situation 00:02:667. 00:03:554 make this slider on 1 bit, that is, start -1-2-3-4, on the white or red part of the bit (red in this situation) 00:03:635. Look at these situations in other parts of the map, remember that the beat starts on white, and thus the guitar sound, drum beats, vocals, etc. start there.
When it comes to combo streams I mean flow which in the cases I mentioned simply disappears after the end of the combo. In simpler terms, a stream that is smooth/rounded turns into a curve with the next combo.
In my opinion, you could do something like this. It will add contrast and won't be confused with the stream. https://drive.google.com/file/d/1_j4uNFmEqa_EMaJH9wOgW-TBVSW9R1Pn/view?usp=sharing
In my opinion, you could simply move this object 00:10:120 (3), because in the game it is easy to mistake this for a buster stream (1,2,3)
