Yeah, that happen sometimes, it's a blue windows with :
"Windows protected your PC
Microsoft Defender SmartScreen prevented an unrecognized app from starting. Running this app might put your PC at risk."
?
That sometimes happen, the more people play it, the less it happen. It's either "Pay to register your program to Windows" or "Make people use it enough so it doesn't happen"
It's up to you if you want to try it or not, though, if my game was a virus, I hope Itch.io would have banned me before 😅
If this is not the message you've got, than could I have some screenchot at "Unifoxgamestudio@gmail.com" ? Thank
