Offset should be 655
General:
Is the goal of this map to be a .osu v3? Because if it is, I can excuse some things, such as no hitsound volume adjustment, slider bodies with hitsounds, but if not I really think you should make some changes here. The whistles on the sliderbodies are really jarring. It’s much better to place the hitsounds on the slider head of the body, rather than the entire slider. Also you should turn your hitsound volume down to like 75%
If your goal is to have this be playable on any osu! client, you should still make a few changes. All perfect curve sliders such as 00:34:256 (1,2), 00:48:102 (2) - on snow, and basically all curved slider’s on Shinku’s diff should be changed to a bezier. This would be easiest to do on my modded b20130303 client. You would also need to make the AR and OD values match.
Diff names here don’t really give players much context as to what they are getting into. Naming your diff Snow implies it’s the harder difficulty by modern mapping conventions, but Shinku’s diff is harder in actuality. I think you should come up with diff names that show some progression. It doesn’t have to be Easy, Hard. But something for players to understand which is which. How about Snow, and Shinku’s Blizzard?
I think the difficulties look fine overall, they just need some sense of direction with hitsounding, and hitsound volume.
Snow:
This diff should not have a higher HP drain as it’s the easier difficulty
Shinku’s:
Shinku’s what…? As I said previously let’s give these names that show progression of difficulty.
