Screen offset?
If you're still braving playing on Kongregate, they made some crazy changes to the UI. You can access your account externally (check discord) or to make it work here, shrink the browser webpage's width and it'll adjust.
Unfortunately I have no control over what they did to the canvas, and nothing was changed on my end (for years now) on sizing or anything. This is on Kongregate to resolve.
