wait let me finish my mapset now =w=

this song is sooo good i made a full mapset ♡⸜(˶˃ ᵕ ˂˶)⸝♡

General.
- Try making combo colors more different, especially between the yellow ones (combo color 3 & 4). It was a bit confusing to understand what object goes to which combo with colors.
- Seems like a cut ver from my research. The title should be "I Don't Know (Nightcore & Cut Ver.)" in that case.
- Any special reasons for not using "bg.jpg" as the BG, but "i dont know.jpg" instead? Seems like a waste of 1mb file space, and the SB seems to work properly when "bg.jpg" is setted as the BG.

Normal.
00:33:942 (1) - Remove clap, sounds really random.
00:41:255 (6) - 00:44:067 (2) - Can you try adding a long slider like you did at 00:38:255 (5) - ? The rhythm felt effective for the chorus, but using it only once felt too irregular. Could try it one or two times more.
00:45:942 (1) - Similar suggestion with Insane to start the spinner 1/2 later along the song's beat.

Hard.
00:14:442 (5,6) - You'll want to avoid this kind of overlaps to make visuals clean. There are more space at the right side, so you can try adjusting the position of (5).
00:28:130 (1,4) - Stack.
00:34:130 (1,3) - Missing clap.
00:45:005 (1) - Remove NC? Didn't felt much reason for a single combo object.

Insane.
00:15:942 (1,2) - Stack is off.
00:30:942 - Better adding a beat here. You were mostly using additive rhythms, and there wasn't much reason to leave this empty while there's a prominent vocal behind.
00:47:817 (1) - Starting the spinner from 00:48:005 - seems better along the song.

Map feels promising. One of the pitfalls you'll want to be careful with symmetric mapping is, mapping for the sake of patterns instead of trying to express the song. Your mapping techniques are good enough, though the structure design in reflecting the song in a bigger picture could get better next time. Sharing similar mapping ideas for similar sounds could be one strategy you can take instead of thinking up of a new idea every combo.

I'm up for a nomination once issues are resolved!
