I launched a thread on Ludei's site. They are still cleaning up at GDC i'm sure, so I don't expect much this week.

I wanted to make a list of issues I'm seeing in Cocoon, and ask if anyone has work around.
*Terrible FPS on first load, there is a noticeable lag as it loads everything into memory I am guessing
*9Patch looks terrible on Android (sprites look like noise/static)
*Audio doesn't start
or restart after muted correctly (depends on platform)
*Tiled Backgrounds go fubar when they are smallish (related to 9patch?)
*Particles don't work on iOS, and sometimes buggy on Android (sprites look like noise/static)
