I just downloaded today and it worked fine for me? I'm on Windows 10 and extracted the .zip with 7Zip
I'm on Windows 11 and it works fine for me, with the Itch.IO launcher. My friend is having the same issue you all are, on Windows 11, similar spec laptops. I tried manually downloading my copy of the game, throwing it on a thumb drive, and it launched fine on my friend's computer off the thumb drive. Once I copied the game to the hard disk (literally just copy/paste) it threw this error. I have NO idea what that means, but food for thought
Maybe try putting the game on a USB and see if it launches? If anyone still has one these days.
