Trivia:
- Doing It for the Art: The little touches in this game rival the Mother series.
- He Also Did: Puresabe also did the Rockman New Year hacks, based on the animal zodiacs of Chinese New Year. The 2015 hack featured Sheep Man (Goat). The 2016 hack featured Spark Mandrill (Monkey). The 2017 hack featured Storm Eagle and Chill Penguin (Rooster). The 2018 hack featured Rush (Dog). The 2019 hack features Hyper Storm H (Pig). The 2020 hack features an Elite Mook version of Ratton. The thing that makes the 2016 and 2017 hacks unique is that they're based on Mega Man X1. Turns out Puresabe does more than the Mega Man NES hacks.
- Keep Circulating the Tapes: The leaked 0.01 Kurai release (containing the Bonus Boss fight with Shadow Man) has been taken down at the request of PureSabe, dooming it to this fate. Subverted when it became official in the 0.02 release, at which point it was rereleased.
- What Could Have Been: The Skull Amulet originally cursed Hell Wheel
if you got it by defeating Skull Man with the Recycle Inhaler, but now it protects you from fatal damage from enemies as long as you're above 1 HP.
