Stinki, I think you and I are merging brain waves or something. This is one thing I've always been suprised at of why other more popular comics haven't moved into flash.
I think if you act big and start doing a bunch of this stuff that is innovative and basically "acting" big, you will in the end be big.
Don't know how long it created to do that vs. a regular still comic, but if you could manage 1 episode a week of flash and 1 still episode a week, I think you could really have something going for you.
Focusing on game related subjects that aren't in such closed circles like Penny Arcade, I think you could really have something quite cool. Just my 2 cents.
P.S. I love how he looks when he's flying backwards.
EDIT: No audio is ok, but as you get more advanced and plan on getting it larger, moving into full audio for characters too could be a phase of growing.
