- The arc note movements are tame for a level 8, and all the notes are in relatively easy positions. If this is your first time seeing sky notes, there are parts that are easy to trip on, but at this level they're not that mean to you.
- What makes this a level 8 is the string of eighth notes near the end of the song. If you're still trying to clear, getting through this part without your gauge plummeting will be what makes or breaks it.
- Before patch 1.1.6, this song cost less Fragments but also required you to clear Clotho and the stargazer for Present and Future difficulties.
- The song has also appear in STELLIGHTS, in which the title is capitalized as "Rabbit in the Black Room".
