As per your request:
[General]
What an odd resolution for the bg... oh well. It's 4:3 still, hehe. It's cute too~ <3
01:21:612 - I recommend putting the preview time here, that way the fade in doesn't affect the vocal.
[Easy]
00:24:182 (5,1) - Hrm, may be confusing as to when this repeating slider is going to end for easy players. Please try something different here.
00:38:840 - Uh, return this extended break back to where it goes by default please.
00:54:696 (5) - New combo
00:58:983 (1) - Not a very good place for a spinner on this level of difficulty. It's kind of short and sudden. I recommend you just map through this with maybe a long slider.
01:31:382 (5,1) - Same thing as before. Please try a different pattern/rhythm.
01:43:897 (1) - Kind of a short spinner again... maybe start it from 01:42:697 - ?
02:01:896 (5) - New combo
02:06:182 (1) - Not a very good place for a spinner on this level of difficulty. It's kind of short and sudden. I recommend you just map through this with maybe a long slider.
02:12:182 (5) - I really don't recommend you make stacks under sliders in Easy difficulties. Hard to discern the rhythm.
02:17:325 (5) - ^
02:38:582 (5,1) - Yup, same as before
02:51:096 (1) - Same suggestion as before
[Apriy's Normal]
4 objects unsnapped!
00:27:953 (1,2) - Move these two back to the red tick, starting at 00:27:783 - . If you do, add a beat at 00:29:326 - and start 00:30:011 (5) - at 00:30:183 -
00:32:411 (3) - Remove a repeat
01:02:582 (6) - Move this to 01:02:412 - and it'll even be spaced more correctly
01:13:553 (6) - Same suggestion here
01:09:439 (3,1) - Eh, spacing is a bit close here.
Same rhythm change suggestions from the previous chorus
01:45:097 - Extend the beginning of the break to here?
02:09:782 (6) - etc
02:10:126 - Insert a break please
02:20:753 (6) - etc
02:21:440 - Insert a break please
02:42:353 (1) - etc
[Hard+]
00:38:840 - Please return this extended break to where it goes by default
01:46:040 - ^
03:03:269 - End the break extension here instead of where it is now.
03:33:268 (4) - Maybe reduce one repeat and start the spinner right after this?
Fun, but definitely fitting of the Hard+ tag.
[Insane]
18 objects not snapped!
01:31:039 (3,1) - This didn't feel like a good place for a stack. It breaks the general motions that you have set up and feels jarring.
Gaaah, I keep failing at the last section because of so many returning overlaps. ;_;
The harder difficulties are good - give some good focus on the easier ones. I am also kind of worried about the difficulty jump between Normal and Hard+, but a difficulty inbetween would be kind of dumb.
