- Another version of this song can be found in Cytus, which is another game made by Rayark.
- This song is actually a modified version of a cut from "Entrance: Hiroshima Striker Edition" which is a remix of the full original song.
- The cursive writing behind Deemo says "givemoney" repeatedly.
- As of Deemo 3.0, the song itself has been updated, and the Extra chart features slide notes that vaguely spell out "EX". The charts of the other difficulties remain unchanged.
