I applied the beta test of Defold Engine, this is free if you want have it a look.
It's there:
http://www.defold.com/One thing I don't very like it is that the project have to be create on their site dashboard and connect your account to google+, and you need to sign-in to use their editor.
However Defold Engine is what Enigma should be, don't get me wrong Engima is cool but Defold is very well polished and most things are tightly integrated. Defold is also written in JAVA and have cross-platform export capabilities to Desktop/Mobile/HTML5.
The Defold site plays the rule of repositories, stores your data, and need constantly be online is a put off for as concerning of usability and privacy, but to be honest it works out pretty well.
