Please, assign an hotkey for fullscreen switch, else than escape, because escape is already taken for closing menus. Usually games use F11 or F4 for fullscreen, why not Crusaders of the Lost Idols?

(P.S : I'm French, sorry if there's any english mistake !)

it could be as simple as using the letter F as a toggle. to go into full screen, and to come out of full screen instead of assigning some other key to one half of that.

f is how one turns on full screen in each and every game ever made by these developers. is the only key for it.

yes, i was kind of making a suggestion the F should be both to get in and to get out of full screen mode.
F i thought was a flash defined key for Full screen but i think it is simply what these Devs defined. and i find it strange it is not listed in the user guide for hotkeys, wonder what other keys they also expect everyone to know.
