About the .mp3, I have to agree it's a bit strange at the end. Maybe just fade out from 02:41:778 or something, because it brutally stops at 02:43:265 when the last sound isn't finished yet >.<
Maybe it's fine though, but as the end of the map is only a few seconds before, it could be kinda.. disturbing if you leave the score panel opened (that's the main problem of non-faded .mp3s >.<)
Tags : you only changed "Natteke" to "Natteke_Desu" in [Hard], add it to every difficulties.
It's anyway an useless tags because _ doesn't work as a space in search mode D: See
this for example xD; Just add "Natteke desu" or "desu" (as Natteke is the artist) since underscores doesn't work.
The map is really fine after rechecking and retesting so I'm just gonna
nazi suggest a few things:
Skin : really nice, I always liked those hitcircles <3, but the map would look even cooler, in my opinion, if you complete it a little more (blue-colored HP bar, etc, so it fits the map well)
Relaxing : HP Drain Rate -1?
Natteke : it's really a suggestion but, I find [Natteke] a bit cold for a diff name. It sure is fine but I'd rather see something like "Natteke's Dream" or.. whatever you want.
Hard : I like your hitsounds <3
Get it ranked <3
