I played one of the games here where the designer had used a black background. The thing is, the black background only occupied a portion of the screen's centre. Is it possible to have the whole screen in black, so that my game will look like the ones from the 70s/80s that I used to play on my Acorn Electron?

Thanks in advance.

Click game in the left panel then click display. Select background to be black. Then you can change the width of that to cover the entire screen. There's also a 'theme' called retro which will make it black and use a retro font.

Thanks, Silver. I'm very excited about this, but it's all very daunting.

How do I find the theme, and also, how do I choose the font colour? It says I can use hex codes, but I don't see where I can enter them?

And, can I left-align the title and subtitle?
