Well, you kinda had me at zombie kittens with laser beam eyes, so ...
Nice flash work. There were a couple moments where the music (mostly the shots of a kitten with the guitar over it) had me thinking Bunnykill, but I am not sure why.
Spoiler: The cross eyed cat is brilliant writing. One of those things that may not work for everyone, but I thought the effect that had on his lasers was hilarious.
I am going back and forth on one thing though. I almost feel like the pacing is a little on the slower side. I think its effective at certain points, but at others it seems that there should be more happening and happening faster. Still simple, as in the main style - but somehow with less of a static feel.
Either way, good stuff - interested to see how the story/style develops as you go along.
