Very touching.
This is really a good tribute to Newgrounds. Relatively speaking, the art, sound, and humor aren't very good, but then again less than 1% of what is submitted to Newgrounds is "high quality." That is why the work of a hodgepodge of amateurs is the most meaningful tribute Newgrounds could get.
The few elite artists, although grateful for Newgrounds I'm sure, do not need it. They could always hone their skills and support themselves on their own websites. But for the amateurs, Newgrounds is the best, maybe the only medium that they can make themselves known in.
That is why, despite the lack of polish, this flash conveys more energy and emotion than something of much higher caliber. Newgrounds belongs to the people who made this flash, and they are grateful for it.
