I have tried looking into what it was that you are speaking off. I have not found any notice or mention of it being flagged. It might have been flagged since I did submit the game to multiple game jams in hopes for it to be played (it is indeed relevant to this one especially). But if you are trying to download the windows installer and it is saying that it is not common and may be unsafe is not something I can control. I am a MacOS user but for Windows from what I have tested because of Windows Defender it often blocks a strong portion of games downloaded from it being not commonly downloaded. If you feel comfortable you are open to navigate it and click download anyway. It downloads the installer for the game. If you have an anti-virus software you can scan the download as well so you can be extra safe. If that is not the issue please show a screenshot here. I tried looking for an notice on here but had not found anything so I am assuming that is what you mean!
