Can you please tell us what exactly you mean by you can't extract it?
The archive is WinZip: https://www.7-zip.org/
You can also download the official itch application and use that to run the game:
In the download description link there is also a link to the steam download page.
I hope this helps.
My environment is unique... I'm using Linux and test Windows games using Wine
https://www.winehq.org/
So I download the .zip twice and each time it refused to extract in Linux. I was able t o download and play Them and Us in Steam (with Proton a fork of Wine) and it ran beautifully. In fact, I loved it so much I might even buy the game!
But if anyone else reports that the zip doesn't extract, it might be corrupting during the download process.
Is there a Linux version planned?
