You had me at "WHEEEEEEEEE~"
I clicked the link, not expecting much more than another mediocre flash slapped together by a middle-schooler......
I left the page, 5 minutes later, a heaping, sobbing pile of human emotion. This story has moved me, it is the pinnacle of what all writers and creators are striving for in today's modern age. Absolutely beautiful, I loved the clever twist at the end, where zombie clown ate bro. Never have I grieved so much over the loss of a fictional character than for bro. In fact, I grieved less at my parent's double funeral, after they both simutaneously died of cancer and aids, respectively.
I commend you for your wonderful contribution to humanity, and look forward to your future masterpieces.
The only suggestion I can think of is to prolong the story, so I might chance upon enjoying a few more moments of this godly story.
