good not great
First thing--"consternation" isn't a particularly "cool" word. It has somewhat humorous connotations. That's not necessarily bad, but it might not be what you intended.
This seemed to move a bit slower than most of the other ones, which is good because it makes each death count.
There were too many words shown and it overdid the whole "inside a computer" thing. Also, the Clown should have been a bit more powerful--if he is a huge flaming skull head, he should be able to burn through a door or a wall as if it were vapor, not have to smash it open.
I didn't like the music. It didn't have much life to it compared to some of the other Madnesses where the music drove the flash. It would be more interesting if it had maybe a happy polka behind it to contrast to the violence.
Overall it's well-executed and develops the story (showing that it's all a training simulation for Hank). But it could be better.
