itch.io

I don't think this is the case. My screen is 2560 pixels wide. I did try testing this on safari and it was as you said. When I changed the size of my browser to be less than 1000px, the game got cut off. This seems to be different on google chrome, which is what I am using. Here is a screenshot.

Why doesn't this game fit in my browser? It is cut off both vertically and horizontally.

This might be a mac issue, I tried it on a windows computer and it worked fine.
