Currently, as shown in the example above, "Sick!" judgments have a visual effect of popping notes, and Long notes have a visual effect of fluttering.

However, Week 6 does not have this visual effect. The lack of visual effects in Week 6 is a major drawback, considering the aforementioned visual effects have a huge impact on how pleasing to the eye they are. In fact, while the charts in Week 6 are certainly interesting, the lack of visual effects makes them feel quite boring. It would be nice to have a dedicated visual effect for Week 6

I assume they're still working on making pixel version of the note splashes and hold covers. Before 0.3.0, Week 6 used the regular note splashes, but this has since been removed.

I believe this is confirmed to be happening at some point.
