I totally agree - I've removed the "hacky workaround" guide, even though it's definitely a false positive, it's never reasonable to ask players to add an exclusion. I also heard from some Windows users that it was only detected as potentially malicious when downloaded via Chrome, but without the Windows Defender trojan warning (like on my PC), so it may still be good for some cases.
All in all this is unfortunate - I've just read a bit about it and it seems to be more or less random for unknown / new apps that have not been used by large amounts of people - I'll research more about the options there to sign the app - allthought at first glance it looked like you'd need a company to proplery sign a build.
Maybe some more details: I come from a Unity/Unreal Engine background and have only recently switched to doing custom engines in C++, so this virus detection issue was never an issue before with the trusty pre-built engines off the shelf. So these are some new challenges for me to tackle.
Anyway, thanks for pointing this out and trying the game out!
