I don't think it's accepting keyboard input.
It's quite funny, lots of games have had this issue including mine. And because it's a game maker jam, hopefully YoYo will see and fix it!

Hi @PelicanPolice
Which keys did you use and which browser? Your feedback will be extremely helpful to us GMS users to pin down the pattern of this "feature". :)
In the menu the keys are Up, Down, and Enter keys.
In the game (if the player did not disable Mouse in the Options Menu), the keys are:
Move : WASD
Shoot : Left Click with Mouse
Aim: Mouse
https://github.com/Kodiqi/WindowFocusThank you @PelicanPolice!
That information pointed me to a direction. I can confirm that I have the same issue on my Linux machine an Chrome, however things work fine on my Win8.1 machine.
The good news is, I found some sources that point to causes and solutions.
Basically, some say it's something YoYo Games did in their patch sometime since November 2020. Someone mentioned that a workaround is to programmatically set window focus somewhere somehow someway. I will investigate and if it works, I will spread the news. :)
