Pixel Monika and Pixel BF sprites: https://fridaynightfunking.fandom.com/wiki/Doki_Doki_Takeover
BF sprites (From Spread the Word): https://fridaynightfunking.fandom.com/wiki/Smile_Dog
(I edited the sprite to fit the pixel look of the video)
Glitched Pixel Monika: https://fridaynightfunking.fandom.com/wiki/Vs._Monika.EXE
Backgrounds (Week 6 & Your demise): https://fridaynightfunking.fandom.com/wiki/Doki_Doki_Takeover
