As per your request:

Disable countdown since it's not being used.
[Normal]
Hrm, the difficulty settings are pretty high for the easiest difficulty of the set. Perhaps lower AR by 1 or 2?
00:51:274 (1,2) - I think the combination of having the larger spacing with 00:49:719 (1,2,3,4) - and you not going with the vocals here made this very strange to read correctly.
For the most part, all of your notes after spinners are far too soon for the easiest difficulty. New players need a lot of recovery time to realign their cursor. Giving one beat at 135 BPM is too little. 2-3 beats feels about right for a decent amount of recovery time. I don't really know what to suggest with what you have mapped though: it may be best to map through the spinners except for maybe 00:13:719 (1) - though that too is still kind of pushing it.
Otherwise this is really nice.

01:12:163 (34) - I dunno, I kind of liked all of these as DON instead of the one KAT

Hrm, maybe reduce HP drain by 1 or 2? I think if you did that, it would make the map more accessible to players considering the difficulty gap between Normal and this compared to this and Insane.
00:13:941 (5) - Delete? There's nothing there in the music...
00:14:385 (1,2,1) - These... were not expected. They feel like they're going way too far. A 1.5x snap feels much better.
01:12:163 (2,1) - Maybe do 1.5 spacing between these?
If you toned those jumps down a tad, this diff will be a really great Hard difficulty imo.

Really fun. :D
00:45:941 (1) - Copy this code in the .osu (do a search for 45941 to quickly find the line that you need to replace)
160,110,45941,6,2,B|90:110|78:187|90:264|173:264,4,220,2|2|2|2|4
for this:
Really worried about the spinner use in Normal - otherwise this set is pretty nice. Good job!
