This is so much what the project I worked on wishes it could have been.
It was interesting playing the game and seeing how many things were approached similarly, even if most of the stuff in my project never got implemented.
If I open the WebGL player in a browser window on half my screen and don't fullscreen it, it crops off the right edge of the gui. For a second I thought it was a bug in the game, but the HTML padding on the player seemed the primary culprit, preventing the player from occupying a little more space.
