I've tried downloading this game on itch a second time now and it still said the download failed a second time. When i trided downloading this game on a different site I had no issues with the download.
I can't reproduce this issue, seems this problem is not on our side, you can send a message in the discord channel of the game and then I can provide you a direct download link to the game.
You downloaded the game from an unofficial website. Of course, it won't work; there will never be any patches or fixes. That's the point of the official version.
