Pressing F4 will send any RPG Maker MV/MZ game fullscreen (For earlier it's ALT+Enter). If you want it to start, you'll need a plugin or some edit. There is also plugins that add a Fullscreen option to the Options menu.

This basically means that Your Turn To Die can do all of these, but the dev just chose not to bother I guess. Though you can "mod" RPG Maker games so anyone can easily make it Fullscreen by default and make an Android port
