not all maps need flow. this song is much better represented without it in my opinion, and the way notes are snapped to the grid seems like an intentional style choice, which there is nothing inherently wrong with
01:08:342 (1,2,3) - same here, i think you could alternatively increase the spacing here to emphasize, but it may feel odd since the map is almost entirely distance snapped. it is up to you, really, this is just a suggestion!
02:23:290 (1,2,3,1,2,3,1,2,1) - replaced here, you can either flow to a non existent circle, or snap at an angle like shown in this video. https://cdn.discordapp.com/attachments/1120587802984337479/1126216054771814540/2023-07-05_13-19-34.mp4
i find this pattern works best for this section
00:09:820 (1,2,3,4) - 1 and 4 were moved around to make the pattern both flow better and read better. gameplay felt awkward when i tried your suggestion, so i tried something a bit different while getting basically the same result
fixed, but not exactly as said. i could not find a pattern to include the slider without having to fix the rest of the section, so its three circles instead of a slider and one circle.
