Glad that you were able to follow the progress of research I was doing into this field using C2.
In the end, I found a great solution using a hybrid of 2 other pieces of software to achieve great results. I plan on integrating C2 content using iframes to future websites for "game" oriented interactivity and will use the other software for the primary website construction.
Both software were very inexpensive (fifty AUD each) and are a great companion to C2.
The first piece of software is called WYSIWYG Web Builder. There are a lot of imitation web builders out there but the 1 that has it exactly like I wrote it was the 1 I downloaded. You don't have to even buy it really... you can use another WYSIWYG website creation software that's open source called KompoZer 0.7.7
I used that initially to delete the blueprints from out of my pages once I was happy with their layout.
Then for interactive panels where I wanted small file size (google crawable) content.. I added iframe elements and used
Hippo HTML Animator to produce this content.
Hippo exported an animation that I tried to replicate using adobe flash and other SWF compilers as well in the long journey to find it at the smallest file size out of them all.
Using adobe and other flash exporters for the swf format .. I was able to produce a 214kb file
Using another HTML 5 animation software Quicker SWF Animator, I produced a 6 MB file
Using Hippo, I produced a 202kb file. I shocked me that it was slightly smaller than the SWF equivalent.
Anyway, hippo is still young in it's development but has a very active dev and community backing it which was helpful to me. If you're doing a single project, I'd recommend just grabbing a demo of it from their site and building the basic animation / interactive content with this.. you get 30 days before it becomes useless so if you're a fast worker, you'll get it all done before you need to even consider buying it should you be so inclined. I was so amazed I just had to own it haha.
AND... once that's done you can complete the interactivity by taking it above and beyond both of these pieces of software using Construct 2. Together all these 3 pieces of software allow the most creative ... NON-Programmers in the world to generate professional and fast loading content.
Man I love how technology has allowed all types of people to enter the brave new world of truly interactive web page development!
