This SNS/AYS Engine has Visual notes, 3D note skins, Multi-key support, Note count and NPS (individual and/or total), Switchable scroll direction, and Individual scroll speed. Pretty high-effort stuff here! Press 1 to toggle between the individual/total note count and nps, and 2 to show and hide it altogether. (Performance depends on your device, but this is a pretty powerful engine.) I'll be posting small updates in the comments when the changes are not substantial enough to warrant a new version.
