You mean snaking in and snaking out sliders? These are both toggleable options now in lazer. Don't worry about it now though, it's still under heavy development
I mean this: stable(lastest) sliders are like this
:stable(fallback) sliders are like this
What I mean is that the stable fallback sliders have 2 hitcircles and when you start a slider the first hitcircle don't disappear, while the other one (stable latest) first hitcircle disappear
I want to know if there is a osu!next fallback version or a game-option to change the slider style.
