Very fun, nice work! Mechanically, I think it would be much more forgiving if you styled the “both at once” spatulas different to the other spatulas, because otherwise it’s very hard to tell looking back and forth the timing of which one of several close in a row is the double one(s). I went for the M on my first try, getting a 633, I’ll take the D haha. Other nitpick is the ending song fade out could be a lot faster, or you could show the results already as the song is fading out.
Great use of theme, and fun animations - which of course, is the main category for this round!
