I have just tried Fabularium and am very happy with it. I have been using the Text Fiction app until now but it is limited in what game types it will support. But it does have support for color ‘themes’. Dark themes in particular. The description of Fabularium says that text color can be changed, and there is a ‘Background color’ in the settings. But I can not figure out how to change text color. I see nothing like that in the settings. And the background color (default is white) seems to do nothing at all. The initial screens are beautiful! But the harsh black and white of a game screen is quite a let down. I would really like to be able to set up something much like Fabularium’s initial screen colors in the games. I hope color options are on the to-do list.
