The super duper easter egg song!
So well done, so well done. I liked it.
The graphics and style are in the same category. It's a unique artstyle that's easily recognised. The sound matches the animation as all of your other works do, frame by frame. And I persoanlly enjoyed noticing each and every single little easter egg in there. Several references to your own works make it fun as a viewer points out "Hey, isn't that so-and-so from whatever?". These are top notch, all of them. I also liked how the entire animation would not desync if I stopped it by right clicking.
On a side note, here are a few deep easter eggs I noticed that relate to his own works.
Near the beginning, there is a lady wearing a shirt with the word "Nox" on it. Anyone who has seen Hoy te Amo++ knows that there was a reference to Everquest's Nox server in that one as well.
Right after the two girls 'face off', in the super fast set of frames, one of them is of a girl holding a rabbit in front of a boy . This rabbit shows up in many of his other works.
Right after the blue girl and guy swordsmen flirt a little, in the fast set of frames, there are a bunch of kids hugging a snowman who appears as often as the rabbit does.
Anyone who has seen Hoy te amo++ can recognise the battered girl walking along the alleyway and the guy shown right after.
I'm not going to bother with the rest...
