Hello, the animation was not attached to be seen (missing the .swf that needs to be included with the html) but I understand what needs to be changed. I work with flash since it was Macromedia :) and I have years experience with it, and right now named Adobe Animate.(work with it daly)
Also I am good with audio, I have some Ideas how can this be done too.
Please contact me on chat so we can talk about the project. I need to know if the animation is vector or photos based, as I can't see the animation.
And imoprtant: do you have the source (.fla) file?
I can deliver the fixed project files in one day or two.
p.s you can see my portfolio of some of my work. I can send more links in chat.
Thank you
