The paddlers are swimming around the cave, glaring at everything with their googly eyes. I’ve altered the cave colors and made the space a little roomier.

The NPC manager I wrote this weekend handles tens of thousands of paddlers while maintaining a framerate of nearly 60 fps, so I’m pretty happy about that. (Naturally, the secret is not to display all of them at the same time, and I do a lot of GL resource swapping  to keep the GPU memory size sane.)

Next week, I tackle the game mechanism.
