Why?
Why are you shitting yourself over one review that was like 5 words long?
Anyway, here it is broken down.
The joke at the end wasn't really funny. It was kinda lame.
What most people do is play with flash for a few weeks before making their first submission. You obviously didn't want to wait and submitted something absolutely experienceless. There was no sign of easing, fluidity, it was just bad.
Length - A very important factor. This was, what, 10 seconds long? Effort is a necessity if you want to get anywhere here.
The combined forces of no length + crappy animation means that many people will mistake this for spam. And honestly, i don't care what you say, this is in the portal about the same time as your other stick video, and you only did it in one hour... yeah, this is spam.
Nobody likes spam, you're gonna have to spend a little more time on your animations. And i don't think you should submit anything until you have a month's practice with the program.
Anyways, that about sums it up. Sorry it had to be like that, but you aren't contributing to this wonderful asset we call newgrounds. Rather, defacing it.
