Meh
Great idea! Wonderfully origanal and creative! two thoughts on it...
As you know, items drawn in flash can get as big or as small as they want and never lose quality. I see that eachtime it "switched" to a new theme, the "portal" so to speak turned into a JPG and was a litte shakey. What would be cool is if everything you wharped to the new computer, all the ones before it really did justb get smaller, insted of switching to pictures. I can imagen that would be harder, but it would make a better product.
Second thing is, you could have put in more thems and charicters to make the loop longer and more enjoyable. At the end of this flash, I'm thinking "heh, cool idea".... if you made more to go with these, people would be thinking "that was a great flash".
