Osu: Increasing / decreasing circle size over time mod proposal

[vruss]

Describe the new feature:
A mod that changes your CS over time. Similar to the wind-up and wind-down mod.

Proposal designs of the feature:
It could start of very small and gradually increase in size. I think this could be a _fun_ challenge for players. I also think such a mod could be combined with other mods.
The names for such a mod could be Grow or Shrink but they are already taken.

Not relevant for this proposal but if possible, maybe the CS could reflect the intensity of the song?

[vruss]

Is it possible to use the existing ModTimeRamp class currently used by wind-up mod to scale the CS as the map progresses? Or is a new ramp class needed?

[peppy]

The circle size would need to be applied differently to each hitobject, so a new implementation is required.

[bdach]

There's been of influx of requests for changing beatmap parameters and gameplay elements in different ways. Care needs to be taken in deciding whether something should be a mod and how it should be presented to the user, so that the mod collection does not become an inscrutable mess.

The problem is, if one would decrease it to 0 and play a dense map (e.g. The Big Black) it would be VERY difficult.

[vruss]

You could limit it within reasonable limits. And it's not for ranked gameplay.
