Spent the morning profiling and banging my head against the wall, hence all the timing data on screen. Finally figured out why my game was rapidly losing FPS over time. It was all because I forgot to clear my flex canvas before drawing to it, whatever that does.
I think that about wraps up my tech stuff on the graphics, dodgy 3d in flash and all. Time to add a game, or at least some wall doom.
Picture should take you to a “playable” version. There’s nothing to do but move left and right (arrow keys) and you might have to click on the screen after you start the game to gain focus (it is a mystery).
