It didn't let me go out of range, but the resolution doesn't quite match. Otherwise, it's fun and fits the theme well!
So in Godot there is a setting to specify the viewport size and I set that to 1000x600 and did the same on the upload page. When I tested from my desktop on Saturday, it looked just fine. But looking from my laptop I get a similar (but less exaggerated) issue. I'll have to play around with some settings and see if I can get it fixed so that I know better for the next game jam.
