If it shows an option called "more info" or something like that, then click on it and it might give you the option to play anyway.
there isnt, there's just the option to change the configurations and to quit, i tried to change the renderer but both options didn't do anything, as well as all the other ones like the framerate
when i click where the exit button is the normal "do you want to quit" pop-up apears, with the game style and all
is there any way to disable the grey screen ? like a ren'py keyboard shortcut or a comand ?
