The colours are a fresh breath of air in this one. Pastel rainbow and basic rainbow colour schemes have been INSANELY overdone and a vast majority of levels that use them don't even vary them so the result is usually eye-glazingly boring. Unsure how to describe the colours here but the best I can think of is 90s Japanese / East-Asian-influenced posters. Does that make sense

The song is also really funny and genuinely suits the level pretty well
