Game is cutted by half in my website

Hello. I embeded a game I created in my website but the window has been cut by half.

Example:

how do I fix it?

What is the size of your project?

How have you set up your fullscreen in browser property in the project properties?

I suggest using something like 640x720 (depending on the game, though), and using letterbox scale. When using that, the game resizes its size to the user's screen without overdoing it like in here.

That's what I used

and the size is 640, 480 with 0 margins

the project right side is just cut

2 questions:

Does the game work as expected in preview mode?

Could you make a screenshot of your project properties?
