Watercolor Brush - New Version Released for Android!

Here comes the updated version of my simple & free painting tool - Watercolor Brush. This new version is much smoother than the old one.
Build with AIR, this is my first AIR project for mobile platforms.
Newer version for web will come soon and I may also release an IOS version in the future.

Bugs, feedbacks, features requests are welcomed!

Finally, some notes for AIR mobile projets:

1. FileReference.save() works on AIR, but you need some declaration in "application.xml" to enable the save function:
