nvm, I fixed it already.
I've been struggling to find a solution for like 15 minutes and the moment I post this comment I find it.
I want to know why you struggled to find it? Were there any bugs?
I found that using ctrl enter puts it in full screen but the game seems to get confused when you go full screen in that way
Um, What do you mean ctrl enter? I haven't implemented something like that. And I tried it but nothing happened?
On some pcs or laptops it is built into the system that that puts certain apps into full screen. In some cases it could also be alt enter.
