This may not be a bug on your end, but I'm unable to download it. I'm able to download other games from itch.io, but this one consistently shows as "Failed". I can manually restart the failed download and it appears to be progressing but just before it completes it says "Failed - Network Error". I checked the alternative downloads box and nothing changed. Any ideas? I'm in the U.S. using chrome.
Well, it really seems like a server-side issue. I'll send a message to itch.io staff and will post any replies here.
However the game has been downloaded > 100 times just today so there's a possibility the issue is more like a regional thing (like a wide area network limitation). Since you downloaded other games the thing just gets a little more confusing =/.
I'll see what I can do, and thanks for the interest :)
