Easy:
Pros:
-It was somewhat easy, yet mostly enjoyable.
-The length's perfect for this difficulty, also, nice song.
-Nice BG and combo colors, they work well (applies for all difficulties)
-For the most part it was the right mix of repetitive yet not overly so, which is what you want for an Easy.
Cons:
-Spacing feels cramped, but that's not too much of an issue.
-Some sliders, like 00:43:12 (1), overlap in a non-pretty way. I would watch out for sliders like that one and things like 00:44:66 (3) that curve too sharply too soon.
-1/2 repeat sliders can be hard for newbies, especially when close to other notes. Watch out for that!
-1 and a 1/2 long sliders like 00:46:01 (1) feel weird on a difficulty of mostly 1 beat sliders. However, it is not much of an issue.
-Notes 1/2 close to each other, however, like 01:16:97 (1,2) should be stacked in one way or another on Easy difficulties like this. It looks prettier and is easier.
That's all, really. Good overall.
Normal:
Pros:
-It flowed well.
-Nice hitsounds, etc.
-Pretty much most things that applied to Easy.
Cons:
-Spacing felt too cramped.
-The squiggly sliders felt weird, but it's not a real issue.
-02:23:88 (4) - I find this inappropriate for a Normal, sorry. Change please.
Hard:
Pros:
-Flowed really well, I liked it a lot!
-Basically what applies to early difficulties, nice job!
Cons:
-Spacing again felt cramp, about the only gripe I really had.
Delirious:
Pros:
-Almost everything.
Cons:
-Only con was that part with all the squiggly sliders. So confusing... but also very fun.
---------
Good overall. Star!
