I'm not really sure what was going on, but it didn't drag on and on so that was cool. I don't mind a random as hell flash if it doesn't drag on for fifteen minutes.
Although it didn't make a whole lot of sense, I did enjoy the creepy aura it exuded. This is the type of thing that makes me wish I was high while surfing NG because THEN it would REALLY freak me out. lol
Also, I give extra points for a random as hell flash that ISN'T just pointlessly disgusting or offensive, but isn't totally G rated either.
As for the animation, as a first flash it wasn't bad. Honestly, it reminds me of "Kid's Story" in The Animatrix, albeit not quite as smooth. All the same, people paid money for that movie, so you're off to a great start.
All in all, I like this. I'm curious to see what you'll roll out next.
