My Game Builder allows you to make games with JavaScript, Phaser, or no code at all. You can pull up your workstation from anywhere, at anytime, and work together on projects. There is real time "google docs" style collaboration. Any game you see can be viewed with full source to see exactly how every part was put together, and forked to make your own "mod" of it or to just mess around. Tutorials are included for art, programming, or whatever else you want to brush up on.
