I also discovered a few other Octone Ink glitches after uploading this level. This includes:

Roll rendering incorrectly under the effect of Pink Octone ink (She's black and pink rather than pure pink)
Bass rendering incorrectly when using Pile Driver and under the effect of Pink Octone Ink (A few black pixels on his face)
Roll is the only character who can use Break Dash and Slash Claw while under the effect of Black Octone Ink with the attack of the weapons (The dashing particles and the "claw", respectively) staying black
Roll and Bass are the only characters who can use Pile Driver and Flame Sword while under the effect of Octone Ink with the white effects of the weapons turning black
All characters render incorrectly when under the effect of Octone ink while aiming Machine Gun up or down

... And several more visual errors. This sort of makes me wish I was a beta tester for Mega Man Maker. If that were the case, these stray pixels wouldn't be as prominent.
