we want to use a more modern engine so we can implement new stuff like fullscreen, maybe an android port
RPG Maker MV and MZ can do both of those though

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
