God, this animation is so smooth and filled to the brim with life! The choreography to the music was amazing. The level of detail in the interior of the house is outstanding. And I'm a big fan of the anime art style.
My favorite scene is when Nelly (the woman) goes complete ham in attempt to swat the fly because of how fast and fluid her movement is as well as the scenery in the background.
Mousekliks, wherever you are, just know that even after all these years, there are still people enjoying the animations you've made.
