Thanks for the heads up! I've been working through the errors, but I've decided to just remove the WebGL option altogether because even once I got it working the game just runs like a slideshow... Better off just downloading it.
I don't want to tell you how to maintain your own project, but I'm probably not the only person who's far more likely to play Web games than downloadable ones. :)
I'll try to give this a shot regardless, though. The concept is interesting.
