Very, very good!
That was amazingly fun! some problems with it though. You should make it so that it doesn't automatically start a song when you go to a new page (by page I mean like when you go to create speach bubbles or characters). If you're already playing a song and you go into a differant page, it plays both songs at once. I also had trouble with speach bubbles. If I'm trying to write in them and say I want to delete what you wrote by outlining it and pressing delete, I can't because it moves the whole thing...so I suggest making the bubble only draggable by the tail (``)

That part, lol. And maybe it's just me, but the space to put the bubble so it appears when you go back is too far down. I think that just be because I have the Screen Area in my settings set to 800 X 600. Unfortunatly there's one more bug. If you create 2 of the same character, when you create the second one, it goes on top of the previous one. So both characters are on top of eachother as one object and you cannot seperate them. Other than that the whole flash was just really great! I can't wait for it to be done!
