Suggestion mod time! Don't worry, no essay. XD
Anyway
[Normal]
Sounds good enough to me, I'll leave this. XD
[Hard]
01:14:847 (1) - When I first heard the start of this verse, I couldn't understand it because of the hitsounds (especially the whistle and clap combo) . It doesn't seem to sound like any sense to me. Or it could just be that I am modding really late. :/
01:24:668 (1,4) - I don't think whistle sounds right here, when the song is winding down in the chorus. XD
01:28:760 (4) - ^ At least you are trying to strike some form of consistency here, I guess... XD XD
01:33:671 (1,3,5,7) - Whis--- Yeah, okay, maybe I am just being really sensitive to the whistle. My point is that this is the slower part of the song, more serious singing, not as much raspy singing or screechy guitar, so, whistle just sounds off. But then, this is just me and I have never been a fan of whistle. Well, you get my point. So, there are a few examples. :3
02:19:228 (1) - Same thing as 01:14:847 (1). XD
02:29:049 (1) - Same thing as 01:24:668... well, you probably get my point anyway, so moving along now. XD
02:45:963 (4) - Isn't this considered a partially hidden slider, since both the head and tail are covered?
[Insane]
01:41:582 (4) - Yeah, I don't know about that slider too. Hahaha. XD
Generally, Insane is a great map. It looks really fun, but I doubt I could play it. XD XD
What I said about the chorus and whistle still applies to insane, but I have a feeling this is more of a preference thing, since your consistent usage of the whistle suggests that you know what you are doing.
Anyway, the biggest things to note are probably the partially hidden sliders, I think it is better to have the head and tail of the slider out in the open, though it might be a bit uglier.
I am also really iffy about that 01:14:847 and 02:19:228 in Hard. It came out really nicely in Insane, but it just sounds confusing in Hard.
It is a great mapset though. So, here is another BAT star. Get back to me, maybe I could bubble it (or maybe Remmy could mod it before I bubble).
