I wanted to know why the need for Adobe Animate (or Adobe Flash CS3)? Could you not use a normal vetor program? I'm basing that on having edited some of the characters from your asset pack 1.
A normal vector program wouldn't be able to insert the code required to create the templates. To my knowledge, anything that can export an SWF with ActionScript is sufficient though.
After a quick scan the other day, I found a few free programs that can handle the SWF format. I didn't write any down because I'm not there yet, but there were a few.
