The first three hitsounds you mentioned, were taken from the Original Skin, so there is no need to change them. The Fade out of the Finish sound reaches until the end of the file, even though it is barely audible, and the fade in of the whistle is intentional by the skin's creators.
I am using the Original Sliderslide now instead of a lower volume one, to fix that issue.
I want to keep my background, but I added 2 more combo colors for more variety.
I don't really want to end the kiais later.. the part feels too calm for kiai, I don't know, it just doesn't feel right to me.
For Easy, I think those multiple repeat sliders are readable as they are long enough, and they fit the song perfectly in those spots. And I don't think they are creativity-less, as you won't find them in many maps nowadays :b
Thank you so much for the great mod! <3
