bug: mouse-look doesn't give the full 360 in a single pass, and unfocusing and refocusing the browser doesn't adjust the center-point of mouse-look. (common solution with most browser-games with this issue)
I am aware of this bug. At the time of creation, I had not yet learned how to lock the cursor, so in windowed mode this becomes an issue. I plan on re-visiting my code after graduating to fix this issue.
