Just wanted to share our project which we have been working on for 10 months already. This is online 2D game editor based on popular JavaScript framework Phaser. We call it MightyEditor. Basically you can create a game in a browser. No need for installing or configuring any advanced software. Also sharing game projects is very easy - works something like Google Docs but for games

MightyEditor comes with a bunch of features: asset management, map editing, tween animation tool, physics, code editor. And very soon we will launch one click export to mobile devices (Crosswalk, Cordova, CocoonJS).

We have open sourced big part of it, check GitHub. You might find useful also tutorials, feature description and twitter.
