Berkili4, would love to use this one... have you thought about getting your game into Microsoft's list of known publishers? My Microsoft Defender SmartScreen blocks it since it cannot validate it is a safe publisher.
Do you have any other 3rd party verifiers to confirm the safety of the game/app? -- If so, that would be worth publishing in your doc to the community.
I believe it to be safe, and the warning has an easy menu to add it as an exception, but I wanted to make you aware in case you want to get it published so that it is recognized in the future properly. It will also likely have increased use / membership since it will be more easily recognized as safe. Most of the games I have used on itch.io do not give that warning so I assume they are registering the other games' software somehow with Microsoft's list of known publishers.
I pasted the image so you can see what message people will get.
