Unlike other itch.io games, the main "Download" button on the https://skeletonbiz.itch.io/vignettes page doesn't work. It's not even a clickable element.

Firefox / Windows 10.

Weird, just tried it and it worked for me . Did you get the game through the bundle? If so, you should be able to download the game in "My Purchases" under "My Library" from the top right menu.

Just tried to download this myself and found the exact same problem using Firefox on Gentoo Linuxand, like mcandre says, i've not had this issue elsewhere .  Will try other browsers and see if I get the same result...

...Yep, can confirm that I have the same issue in Vivaldi,  Opera and SeaMonkey.  However, as suggested, I can download it from the My Purchases page just fine.   Bit odd but at least it's not a show-stopper.

Same on Safari/Mac. Had to go in the back way as described.

Just pointing out that the issue still persists in all my browsers on two different systems. Downloading it via the library works, but the download button on the game page itself is broken.
