1. Click the Download button above

2. Right click the .Zip file --> Extract All

3. Open the unzipped folder and right click on Redback.exe. Click on Properties (the popup on the right should show up) 

4. Tick the checkbox Unblock. After doing this the box will disappear, you only need to do this once.

5. Now the game should run every time, e.g double click the .exe

The game isn't a virus but gets silently blocked because I don't have a licensed digital certificate. I dunno how else to do it without directly sharing with every person

METHOD 2:

The download and installation process above only outlines pre-set versions of the files uploaded, meaning future updates to the game require repeated downloads (if you ever choose to play again). While unlikely, if you are someone who will continue playing, you can receive automatic updates (similar to Steam) by first installing the Itch.io launcher at https://itch.io/app/download. Downloading the game through their launcher also skips the process above, all you have to do is paste the link of this website in the app's search bar and it should do the rest for you - the only drawback is that you have to create an account.
