This should be part of the export options as a small checkbox.
To change the game size, press esc.
Not sure if you can change the game size if you didn’t check the full screen checkbox.
@GameDaGameMaker - what platform are you exporting to? Mac, Windows, iPhone?
Hey @GameDaGameMaker - it looks like there is an issue with the scaling on Windows, I’ll check it out and let you know when it’s fixed.
@grazer ok thanks
Hey @GameDaGameMaker - try re-exporting the game, and I think the fullscreen issues should be sorted out.
