Painfull
It was actually quite hard to watch through all of the animation, It was crap.
I don't want to seem like an asshole, because it was obvious that you actually put effort into it. You didnt intend in spamming the portal with bollocks.
The story was a massive failure, half of the entire fucking animation was just a guy driving in a car why not just put "Later that Day" or something?
The drawing was rubbish, the only drawing tool you used was the rectangle, and circles for the 'target'... also that "Which target do I shoot?" joke, was god awfull.
The animation... well the only animation was a car driving (which the driver was just a pink hovering square but nervermind) ((more like floating as there was no visible wheel movement)) and a guy answering his brick, which was smooth, but boring.
The worst part of the flash... the voice acting... GOD! You can download sounds from the internet, not every sound effect in the ENTIRE flash has to be your own, immature sounding (No offence) voice, "DE DE DE DE DE, HELLO MOTTO" made sigh. After everytime you spoke you made a shit load of feedback/static, get a better mic.
Do these changes and you could have a passable, portal worthy flash.
Also, the blue dude... didnt he die in London 1984... but then magicly appear in London 2009.
