Moving to Unity
Well, when I had most of my game code ready on a Javascript framework to produce multi-platform HTML5 games I realised that speed would be a serious issue for the mobile versions of the games :-(
But, as they say, when a door closes another opens. Fortunately there is now a Linux Unity version and I started moving the games to that. Hopefully I'll have something to show soon. Not only that but I see that Unity has a good system to distribute the assets I have already built ... might be a win-win situation after all! :-)
