It's been a long few weeks, but I've finally managed to figure out a way to stop Windows Defender and Norton from blocking my game. For good. Thanks so much to everyone for dealing with this, because I know how valuable a clean computer is.
Also I've removed the "multiplayer" and "co-op" tags from the store page to avoid confusion, since it's only local multiplayer.
There's nothing too exciting to say because I've been spending most of my time on my other project, so if you're curious, you can find more info on my website: http://www.vastforecast.com/
Thank you, and until next time!
