That's a common issue that actually [So no big deal] has happened with us when we downloaded some of the games on the jam, however we fixed the issue & got a lot of people to try it!! So try again if it doesn't work then that's unfortunate & we hope of finding a way to play our game.
Yeah I've gotten it a few times as well as I've been playing em. I went back and tried redownloading it again and got the same error - which is very unfortunate your game looks so well made. I'm sorry!
