Soon as how I'm no longer making my mystery game, I guess the question is: what am I going to do now? The next game I'll make will probably be Switch's sequel game, but I haven't started work on that yet.
Instead I've decided to experiment with 3D. I've already got some xml model importing (using my own proprietary xml model file format) and the 3D positioning is brilliant. Still no rotation yet, but rome wasn't built in one day, you know.
