Trivia / Touhou Suimusou ~ Immaterial and Missing Power

• Throw It In!: Twilight Frontier started implementing Mauve Shirt character Hong Meiling into the game without asking ZUN, which is why she has no Story Mode and doesn't reappear in the next fighting game (though she does in its expansion pack).
• What Could Have Been: Like the games that came before it, there was originally going to be SC-88Pro-compatible MIDIs that you could toggle between. However, they could not fit on the 700 MB CDs the game was burned on. This is also the reason why the game's soundtrack is formatted in OGG instead of the usual WAV.
