Google download link not working and mega is pretty trash, limiting progress and making the download take days. I would recommend looking into alternative file hosting services, or just update the steam demo to the currently available update.
Your guess is as good as mine. My reply was in response to a link that was posted to an illegal download, not the page itself. This page is completely legit, but you're right, I was just trying to look out for people.
My guess would be that I was being downvoted by the actual pirates who want everything for free rather than to support a solo dev and his project.
