Yes, that's all you can do in the last uploaded version (plus zoom in/out with I/O and look at some debug stuff with L). I didn't manage to get real gameplay in there by the end of the demo day- I hope to have something more polished the next time we do something like this.
Thanks for giving it a download and play! And thanks for the heads-up on the memory leak- turns out I didn't understand how you're meant to use openGL fence syncs. I thought you called glFenceSync every frame to synchronize stuff, but that actually creates a new fence object. Whoops! It's fixed now, and the memory leak is gone. Thank you!
