Worked out what it is... because I have Windows UI scaling on the frame Itch uses is scaled up HOWEVER your game is trying not to scale (in menus and the UI aspects including the extra labels) but is scaling in the viewport (so I actually see further when playing...)
in my projects I (at the moment) always set "Display" -> "window" -> "Stretch" -> "Mode" to 2d and "Display" -> "window" -> "Stretch" -> "Aspect" to know what it is going to look like on all screen resolutions.
