Yesterday I bought two licenses after extensive testing (also other applications).
As a result Sencha Animator came out the best for what we wanted to do with it.
So keep up the great work.
Although as you may know, there is a little competition in this type of application (Adobe Edge, Tumult Hype for example).
There is that and there is also a very nice open source library for this created by the guys who created the HTML5 version of the populair iPad game : Cut the Rope HD http://thinkpixellab.com/pxloader/
I would really love to see this feature in the future!
