Modding: (just going through random threads :3)
class A(npan)00:11:911 (2,3) - The timing at the end of the slider and the next slider doesn't sync with the music, consider moving it slightly earlier to fix this (the slider velocity change at '3', is good though, keep that
00:16:142 (7,1) - Slider 7 goes for too long and doesn't allow the next 2 sliders to match with the song, instead, shorten slider 7 and shift slider 1 back so they are rhythmically closer to each other, as a consequence of this, also move them (visually) closer together to flow better
01:14:026 (3,4,5,6,7,8,1) - To match with the piano gliss in the song, consider shortening slider 3 and then shifting the mini stream to be slightly earlier to make the gliss feel more seamless (though the timing now is nearly perfect)
Overall, this is looking pretty good! So far it look like you've made a TV size map but you have left a lot of the music in, are you planning on lengthening this? If not, probably get rid of the extra music.
Also, planning on making the other difficulties?
Also press Crtl + Shift + a for the Ai mod, have a look at some of the stuff it says from time to time as well (rn it mostly talks about the file size)
Gl for the rest of this, hope this helps!!
