Pretty good
I don't find Salad Fingers to be the most interesting flash out there, because when you get past the randomness it doesn't have that much substance, and judging by some reviews I often get the feeling that many people confuse Tim Burton-esque weirdness with an intellectual, artistic piece. Lots of people do random and weird, and just because this is serious doesn't suddenly elevate it to the towering heights of intellectualism.
So, a parody is always welcome! And contrary to what some other people seem to think, you seem to understand Salad Fingers fully, which is what makes this so funny!
