Hey there,
This is a common issue with smaller games made with Gamemaker unfortunately 😔 because windows does not recognize the software, it flags it as a virus.
If you're concerned, feel free to play the version in browser instead! 😊
Oh wow, that's frustrating. What browser are you trying to launch it in? I will try and test it using the same one to see if I can fix it.
In the most recent update I have added file saving, but I might just remove that from the browser version because it could be the reason it's stopping you from playing! 😊
