It is a Java-based project at its heart that uses GWT to transpile the code into very efficient JavaScript while staying easy to debug and develop.
I am currently working on producing a complete game that I will publish on the Facebook Instant Games platform and others.
The extremely cool thing about this engine is that it records your gameplay and allows you to share it with others. Attached to the project is a unique and efficient algorithm that enables users to share their recorded game using just a URL and no server-side data, as all information about the gameplay is stored in the URL.
