Slowly but surely, I am making progress.
I have now implemented basic character movement in a style similar to the old asteroids games.
For some reason, the movement is very jittery at times, and there seems to be no correlation with the amount of particles. I’ve noticed this happen in other games I’ve been working on too — does anyone know how to address this problem?
I just created the first test build, which you can try out here: http://jceipek.github.com/LudumDare23/
