that was the first thing i thought of. problem is, it is so off center, that i can't even change the resolution. and no amount of uninstalling helps.
if you havnt done so, instal the game with the itch.io app.. i found the normal downloadof the game had more issues than the app.
Also, you can try deleting your settings file to reset everything to default. It can be found on your PC here: C:\Users\YourUserName\AppData\Local\ShopSim\Saved\SaveGames
