Good story so far.
Personally, I was never really pleased with my voice acting for Vile. Thankfully, it was a small role. Aside from that, some of the use of various graphics were pretty awkward. Shadow's appearance is one of them and Link from Zelda. The fight scenes were pretty decent, though I think the Smash Brother references on the "versus" thing were unnecessary. They could've been removed and nothing would have taken effect.
I like the flash so far, and I look foreword to the next installment. Keep Going.
