Simply put, I made a game in 800x600. I set that size on the project upload, and it still runs bigger.
Tried with and without the bar at the bottom, it still doesn't play on the size I choose, but 1000x750
Is it a bug or I'm missing something?
The viewport dimensions sets the direct size of the iframe. If the contents of your project don’t match that exactly then you may have to adjust the viewport dimensions accordingly. If you’re using Unity, then we recommend a minimal template that removes any extra UI that can take up more space: https://seansleblanc.itch.io/better-minimal-webgl-template
