I am from MightyFingers team based in Latvia. We have recently launched HTML5 game engine - MightyEngine. The basic idea is to write JavaScript code and run the game on WEB, IOS and Android. For mobile platforms we use CocoonJS that gives us close to native speed, a much better solution than PhoneGap.

We have also functions like rendering, level editor, asset manager, map editor, UI template system.

It would be great to hear your opinion.
