• The notes change density regularly: from 12ths, to 16ths, and 24ths. Be sure to pay attention at which places you need to speed up or slow down hitting notes in the chart
    • Most of the sky note bursts are 24ths. This include the long 24th run at the end of the song.
    • A lot of the short 24th bursts are a set of 4 notes. Be sure to pay attention which finger would hit the last one.
  • The spiral arc at 1:46 is VERY easy to miss due to how fast it changes flow. After hitting the tick, immediately spiral around and follow the arc so you don't miss.
  • The zig-zag arcs are quite easy to miss as well. Make sure to pay attention where you hit them to compensate for the slight play field shift.
  • The Future chart features several pattern originally from various other songs: SOUNDWiTCH, CROSS†SOUL, Purgatorium, and specially, Grievous Lady. These can be used to practice this chart or the other way around.
