Today's update includes a big performance optimization for build mode. After these optimizations I saw a 40% increase in FPS! I hope you notice the improvement as well!
This build also includes a fix for a bug that caused the camera to be angled slightly in the X axis. Moving the mouse would automatically correct the angle, but it was a bit jarring when that happened the first time you start or load a game so I fixed it.
Still working on the stamina and clicking aspects of combat. Should have the stamina changes done this weekend, then will tackle the click-to-attack changes.
