Simple, yet effective.
That was just plain hilarious. I was somewhat expecting the star to be in pain, or something like that, but the way he suddenly started screaming... damn funny. When he crashed into the mountain was pretty much tearing me up laughing too, especially because of the huge bang while you only hear an echoing "ow". And then the music that followed... please get a mob and wipe me together! I'm still laughing because of that!
But besides that, the sound and graphics were simple in a humorous way, yet somewhat pretty to look at. The animation itself it pretty clean too. You can just see the whole flash has been focused on humor alone -- like it should be in comedy!
Well, a dry-humored plot with a touch of sadistic humor always does the job, eh?
