Thanks. Ah sorry that camera was dizzying. My guess is that with apple hardware the mouse just has a lot of DPI and its very fast, and my crappy 5$ mouse is just slower. Note taken: implement settings in the future, allow mouse speed to be adjusted.
Its a shame that another person got stuck -.- F11 should work, but browsers usually think its some command button (dev console or what not). Didn't check that eh. But it should work in following way, at least in chrome: F4 to quit fullscreen, F11 respawn, F4 to go back to fullscreen.
Thanks for playing!
