Hello:
Some months ago I was looking for an Open Source 2D Game Editor(with a user interface) for JAVA, and didn't find one, in fact I was looking for one with an LGPL license. So that could protect the Game it's self (closed source)but share some common code giving it to the Framework.

I have spent the last 6 months programming a Game Editor for JAVA.
, would  really appreciate your opinions.

According to the slogan "Release Early, Release Often" the project is there so that you  can tell if the project is useful, would really appreciate your opinions.

JXArcade is a 2D Game Editor for JAVA. It allows you to produce Arcade java games using a graphic Interface to define sprites , animated sprites, paths and scene. 
It also provides a consistent framework for game   
development 


The Joystick Input Engine and the Sound Engine  was not implemented intentionally to give
space to every game programmer that feels can contribute to this framework. (Any contribution that makes the framework better will be accepted)
Remember that the license is LGPL, so you can extend the framework and use it even
commercially with out the need to open your source.
