Hey everyone, not sure if this is related to itch or Unity, but I'm trying to have my Unity game appear in fullscreen but it is instead staying the same size while the rest of the screen is black. You can see the effect yourself if you take a look at the projects page:

Does anyone know how to fix this issue?

I haven't used Unity, but I notice that your HTML page has the unityContainer div set to a fixed pixel width/height instead of screen-size-relative units, and this Stackoverflow thread suggests that could be the problem: https://stackoverflow.com/questions/55450290/unity-web-gl-html-container-how-to-...

Thank you very much, this seems to be the correct way to approach the problem!
