This is the error message I received from the itch.io desktop app: "The request signature we calculated does not match the signature you provided. Check your secret access key and signing method."
Very strange. Have you tried downloading it via the website? Just tried it out and it worked. Please be advised that the game will not work for new MacOS versions.
I've tried Firefox browser as well, along with turning off extensions and trying itch.io's alternative download mode. Still couldn't get it working, and I could download other itch.io games fine.
