0.2.1 is out!

After making some good progress, I decided to release 0.2.1 early. The biggest change in this update is that the game now runs at 100 physics time steps (or "ticks") per second, which gives the player higher control and better strafing. I also fixed some minor bugs, added a framerate row to the debug window, and demos can now be saved on all platforms. All other changes mentioned in the older blog post will be added in 0.2.2.
