Hi there from MightyFingers 
We are finally entering beta stage with our HTML5 game engine, so i wanted to share it with you guys.
If you want to join in on the fun, follow this link - http://beta.mightyfingers.com/
MightyEngine is a Javascript HTML5 based cross-platform 2D game engine, that allows you to develop AAA quality 2D games.
It is free for non-commercial use, so feel free to play around with it.
If you have any questions please ask here or in our forum (or mail) - the docs are still in progress, so some things might be missing.
Anyway there is some more info in the blog - http://mightyfingers.com/blog/mightyengine-beta-is-live/
Currently we are preparing it for the normal launch and we would really appreciate your feedback.
