Not funny
I thought it was just awful. Everyone knows damn well that since illwillpress apparently doesn't read reviews these sorts of responses are more directed at the prepubescent oddballs who spend all day here pretending to have a life, but I'll go along with the constructive criticism thing to keep out of trouble.
Background had near zero effort put into it. The pool and everything around it aside from the characters was done with trace bitmap, computer did it all for you. The rant itself wasn't even good. Completely trivial and seems like another side effect of illwillpress's perpetual PMS tantrum. Constructive criticism: Make an animation about something that's either important or funny. Then put actual effort into it.
