@sandlooney you're welcome.
The latest change from kongregate is a bit better in terms of game screen size.
I understand that there may be cases with problems and I may check this.
Personally, I just used this "Custom CSS by Denis" extension in my Brave browser - it uses Google chrome extensions - and by adding this CSS rule
".relative.rounded-lg.w-full.mx-auto {
height: 862.4px!important;
max-height: 862.4px!important;
}"
I was able to avoid having to go full screen every time.
