It happens for many game engines. Godot packed exe are quite a bad offender here. But you will also see false positives for some renpy and rpgmaker. And this gamemaker engine. Possibly others too.
It is a huge problem, since malware is bundled with real games. What is a user to think? Is the antivirus warning a false positive or real positive? So better safe than sorry.
Shame on the game engine makers. And to some extent on the scanner makers. But more on the engine makers. They try to be "clever" in their exe creation. But "clever" is what malware does. We need reliable and obvious. That is also good for less bugs, I would imagine.
