UPDATE: Indeed, changing the page zoom settings centers the window and fixes it, I know how it is trying to set the resolution, window size in the engine then setting it right on the Itch page, it's a nightmare, but once it centered and the offset went away it is very fun! Like the graphics, it's an extremely good foundation, add upgrades, missions, maybe optional people to rescue? And it's kind of tough to click on people, I ended up accidentally sending the wrong people to places because I thought I had clicked on the person I wanted, but other than that it's solid!
