Excellent work on the visuals. However, I would have liked to see a clearer distinction between the monsters appearing in the "good" and "evil" sections of the track. For example, slugs appear in both, and it would have been even more impressive if no monsters from the "good" sections were present in the "evil" ones (maybe except for the green dragons, which are a whole other topic).

Ha ha, amazing! I haven't seen anyone use a background video yet, this chart wouldn't be the same without it.

I'd have loved to seen more contrast in difficulty between the different sections, a lot of other rhythm games keep the start of the song as a beginner level song, so that the scary sections are even more surprising and funny, doubling the BPM with ten times as many notes. But I respect the choice to keep the song consistent throughout too.

Great work on this one!
