Trivia / Touhou Seirensen ~ Undefined Fantastic Object

• Colbert Bump: The game gained more notoriety when it was used as the basis for a joke ransomware program named "Rensenware". It encrypted all of your files until you played the game on Lunatic, and scored at least 200 million points. You also had to go out of your way to get the game, as it wasn't included (and given that it probably already encrypted your web browser... Yeah, good luck with that).
• Throw It In!: Windows XP's balloon tip sound snuck in during the recording process of "Interdimensional Voyage of a Ghostly Passenger Ship". ZUN didn't bother rerecording it because it fit with the rhythm anyway.
