K. Lots of people are pissed.
Honestly, many (but not all) people who bash this haven't even touched flash, so I'll go with the "then do better yourself" approach. The drawing was rather clean, but the animation was lower quality, probably look into using some tweens, to save major hassle between the "stills" while giving animation. Additionally, the music wasn't so horrible, there's easily been a lot worse in the course of NG history. You ask for my take on it, I think tons of people are mad at this because it landed front page without being particularly outstanding, but has anyone noticed the exact same thing happening en mass with front page games? The par was lowered or altered somewhere along the lines if you ask me. Overall, drawing good, expressions stereotypical for anime (not necessarily making this stereotypical anime), but the animation could use a lot of work.
Good luck in future endeavors.
