Pretty trippy
Reminds me of those cartoons you use to see on channel 4 at about 2 am when you come in drunk.. Some of the animation looked good, some didn't and it all looked really abstract which looks like the effect you were going for. I'm not a stoner, but i feel like getting stoned after that cause it has a pretty pointless plot direction. I mean it was ok, watching the man get caught when he was just trying to make the world a better place, but when he starts tunneling it just gets weird.
Also, look into optimising the sound... there's no way that should have been (Almost 10 meg was it?) that much in file size.
Still, look forward to seeing how you develop as a flash artist.
