I've just tried it, it's working great
Few minor things that I found to be off:
--The mouse movement as you mentioned, except it's not really that bad. I had problems only 2-3 times when waiting for doors to open and it lasted about 3 seconds.
--Loading was a bit strange. After clicking the exe windowed-loading bar started, then after it was done there was a pause and then another loading bar in fullscreen started.
Apart from this everything went o.k.
It would be also great to have an ico for exe, this way the exe file seems a bit unidentifiable
