the December game for OneGameAMonth is Glow Fury X, a version of Glow Fury that runs under the PlayCanvas engine. In addition to using 3D graphics this new version runs in-browser using javascript and WebGL, which means that you are not required to use the Unity web player.

Unfortunately, I wasn't very familar with PlayCanvas and so getting even the basic mechanics working took a while. Also, there isn't a standard GUI library so I ended up using HTML DOM elements as a GUI, layering then on top of the render area. While this lets me use all the power of HTML formatting and CSS styling, the DOM really isn't intended for this kind of thing and so it felt pretty clunky. I might get more milage of it next time.

Play Glow Fury X here.
